If it is struck by a rigid block having a weight of 550 lblb and traveling at 2 ft/sft/s , determine the maximum stress in the cylinder. Neglect the mass of the cylinder. Express your answer to three significant figures and include appropriate units.

Answers

Answer 1

This question is incomplete, The missing image is uploaded along this answer below;

Answer:

the maximum stress in the cylinder is 3.23 ksi

 

Explanation:

Given the data in the question and the diagram below;

First we determine the initial Kinetic Energy;

T = [tex]\frac{1}{2}[/tex]mv²

we substitute

⇒ T = [tex]\frac{1}{2}[/tex] × (550/32.2) × (2)²

T = 34.16149 lb.ft

T =  ( 34.16149 × 12 ) lb.in  

T = 409.93788 lb.in

Now, the volume will be;

V = [tex]\frac{\pi }{4}[/tex]d²L

from the diagram; d = 0.5 ft and L = 1.5 ft

so we substitute

V =  [tex]\frac{\pi }{4}[/tex] × ( 0.5 × 12 in )² × ( 1.5 × 12 in )

V = 508.938 in³

So by conservation of energy;

Initial energy per unit volume = Strain energy per volume

⇒ T/V = σ²/2E

from the image; E = 6.48(10⁶) kip

so we substitute

⇒ 409.93788 / 508.938 = σ²/2[6.48(10⁶)]

508.938σ² =  5,312,794,924.8

σ² = 10,438,982.5967  

σ = √10,438,982.5967

σ = 3230.9414  

σ = 3.2309 ksi  ≈ 3.23 ksi    { three significant figures }

Therefore, the maximum stress in the cylinder is 3.23 ksi

Three key criteria are used to determine the cable size: the carrying capacity right now. voltage control. Rating for short circuits. What elements determine the conduit and tubing sizes needed for an installation? Conductor count, cross-sectional area, and permitted raceway fill.

To avoid overheating and fire, the NEC specifies conductor minimum sizes. Three main variables affect how big a conductor needs to be to safely carry the current forced upon it: insulation type, ambient temperature, and conductor bundling.

Kelvin's law determines the appropriate size of the conductor for transmission lines (given by Lord Kelvin in 1881).

Answers

To replace the force system shown in Prob. 4-135 with a wrench, you will need to determine the magnitude and direction of the force and couple moment that the wrench should exert.

You can do this by taking the following actions:

Identify the net force influencing the system: You can accomplish this by adding up the various forces that are at work on the system. The net force in this situation is 200 + 400 = 600 N.

The system's net couple moment can be calculated by: This is accomplished by adding the two moments of the various forces at the wrench's x-z plane intersection. The net couple moment in this scenario is calculated as (0.5 m)(200 N) - (4 m)(200 N) - (3 m)(400 N) = -600 N*m.

Calculate the wrench's pair moment and force, taking into account their magnitude and direction: The equations for the force and couple moment of a wrench can be used for this.

Answers

As a result, induced voltage will drop as the coil's turn count is reduced. This phenomena is explained by Faraday's Law.

According to Faraday's Law, if a conductor is a part of a closed circuit, an electric current will flow whether the conductor is passed through a magnetic field or the magnetic field is moved past the conductor.

We are aware that if a static conductor is placed within a fluctuating magnetic field or if a conductor moves within a static magnetic field, a voltage will be induced. This phenomena is explained by Faraday's Law.

Changes to the magnetic field's strength, the conductor's movement in and out of the field, the distance between a magnet and the conductor, or the size of a loop in the field can all result in this shift.

Answers

Since all processes have a finish value of true, the safe sequence is P2, P3, P1. Therefore, the correct answer is (B) P1, P2, P3.

To find the safe sequence using the Banker's algorithm, you need to perform the following steps:

Calculate the need matrix for each process by subtracting the allocation matrix from the maximum demand matrix.Initialize the work array to the available vector and the finish array to false for all processes.Find a process with a finish value of false that has a need less than or equal to the work array. If such a process is found, allocate resources to that process and update the work and finish arrays.Repeat step 3 until either there are no more processes with a finish value of false or no such process can be found.

Using these steps, we can find the safe sequence for the given scenario as follows:

Need matrix:

P1: 3-2=1, 3-3=0, 3-3=0

P2: 2-1=1, 1-1=0, 0-0=0

P3: 1-1=0, 1-1=0, 1-0=1

Work array: [2, 1, 1]

Finish array: [false, false, false]

Step 1: Process P2 has a need of [1, 0, 0] which is less than or equal to the work array, so it can be allocated resources. Update work array to [2-1=1, 1-0=1, 1-0=1] and set finish[P2]=true.

Work array: [1, 1, 1]

Finish array: [false, true, false]

Step 2: Process P3 has a need of [0, 0, 1] which is less than or equal to the work array, so it can be allocated resources. Update work array to [1-0=1, 1-0=1, 1-1=0] and set finish[P3]=true.

Work array: [1, 1, 0]

Finish array: [false, true, true]

Step 3: Process P1 has a need of [1, 0, 0] which is less than or equal to the work array, so it can be allocated resources. Update work array to [1-1=0, 1-0=1, 0-0=0] and set finish[P1]=true.

Work array: [0, 1, 0]

Finish array: [true, true, true]

â

Answers

Three D-type flip-flops are all that are needed to construct a divide-by-6 counter, also known as a modulo 6 (MOD-6) counter circuit. The counter is set up so that it counts from 0 to 5 and then automatically resets on the sixth count to start over.

It is unstable because we are using the sixth count itself to reset. Start with a MOD-B counter and look for the binary sequence 110, which is 6 in decimal, to get the trick. We look for the sequence of 1s and feed them into an AND gate because this binary sequence is unique. The RESET function on each of the three flip-flops is then controlled by the output of the AND gate. Keep in mind that the counter output is from left to right while binary is read from right to left (LSB to MSB). Here, students are likely to make mistakes and feed the AND gate with the wrong outputs.

One of the most important uses for shift registers is in Johnson counters. They are made by connecting the complement of the output of the last flip-flop to the input of the first flip-flop and connecting multiple flip-flops so that one flip-flop's output serves as the input for another.

A mod 6 Johnson counter requires three flip-flops. Keep in mind that a Johnson counter requires half as many flip-flops as it uses in states. Three flip flops will be needed because a mod 6 Johnson counter can count up to six states.

Because a Johnson counter is a synchronous counter like a ring counter, state transitions cannot occur unless the clock is in the "ON" state.

What i the relationhip between the weight of a Viking boat and water diplacement?

Answers

The weight of the water displaced is calculated as the product of the ship's water displacement volume and water density. Displacement is therefore equal to ship weight.

Every floating object displaces its own weight in the liquid in which it is submerged according to the Archimedes principle. A vessel's weight must match the weight of the volume of water it removes in order for it to float freely in the water. The amount of water that a vessel displaces is known as displacement.

The buoyant force acting on the object will be equal to gravity if it displaces an amount of water equal to its own weight, at which point the object will float. However, if an object weighs more than the volume of water it moves, it will sink since the buoyant force will be greater than gravity.

: A uniform slender rod AB rests on a frictionless horizontal surface, and a force P of magnitude 0.25 lb is applied at A in a direction perpendicular to the rod. Assume that the rod weighs 1.85 lb

Answers

The length of the rod is 0.45 ft and the location of point B is 0.45 ft from point A.The point on the rod that has zero acceleration is located 0.225 ft from point A.

To find the acceleration of point A, we can use Newton's second law of motion, which states that the force acting on an object is equal to the mass of the object times its acceleration.

The total force acting on the rod is the force P at point A and the weight of the rod at point B. The weight of the rod is equal to its mass times the acceleration due to gravity, so the total force is:

F_total = P + m_rod * g

Where m_rod is the mass of the rod and g is the acceleration due to gravity.

The acceleration of point A is then:

a = F_total / m_rod

To find the location of the point on the bar that has zero acceleration, we can use the concept of center of mass.

For a uniform rod, the center of mass is located at the midpoint of the rod.

The linear density of the rod is equal to its mass divided by its length, so the length of the rod is:

L = F_total / (m_rod / L)

Solving for L in terms of the given quantities, we find that the length of the rod is:

L = (P + m_rod * g) / (m_rod / L)

This equation can be rearranged and solved to find the value of L.

L^2 = (P + m_rod * g) / (m_rod / L)

L^3 = P + m_rod * g

L^3 - m_rod * g = P

L = (P / (m_rod * g))^(1/3)

Substituting in the given values, we find that:

L = ((0.25 lb) / (1.85 lb * 32.2 ft/s^2))^(1/3) = 0.45 ft

So the length of the rod is 0.45 ft and the location of point B is 0.45 ft from point A.

Here the calculation to find that the midpoint of the rod:

((0.25 lb) + (1.85 lb * 32.2 ft/s^2)) / (2 * (1.85 lb / L)) = 0.225 ft

So the point on the rod that has zero acceleration is located 0.225 ft from point A.

The missing part in the question is shown below.

A uniform slender rod AB rests on a frictionless horizontal surface, and a force P of magnitude 0.25 lb is applied at A in a direction perpendicular to the rod.

The Fourier transform of each signal :

x[n] = a[n-2] - [n-6] →X(ω) = A(ω)e^2ω - A(ω)e^6ωx[n] = -u[-n-1] → X(ω) = A(ω)e^(-jω) x[n] 2* sin(n)ul-n) → X(ω) = 2A(ω)sin(ω) x[n] = (cos(n-1))  → X(ω) = A(ω)cos(ω-1) x[n] = sin(n) + cos(n) → X(ω) = A(ω) (sin(ω) + cos(ω))x[n] = sin(n) + cos(n)  → X(ω) = A(ω) (sin(ω) + cos(ω))x[n] = x[n-6] + x[n+6] → X(ω) = A(ω) (e^6ω + e^-6ω)

x[n] = a[n-2] - [n-6]

The Fourier transform of a signal x[n] is given by X(ω) = ∑x[n]e^-jnω. In this case, the signal x[n] is a[n-2] - a[n-6], so we can rewrite this as x[n] = a[n]e^2ω - a[n]e^6ω. We can then use the Fourier transform formula to find the Fourier transform of the signal:

X(ω) = ∑(a[n]e^2ω - a[n]e^6ω) e^-jnω

= ∑a[n]e^2ωe^-jnω - ∑a[n]e^6ωe^-jnω

= A(ω)e^2ω - A(ω)e^6ω

Therefore, the Fourier transform of x[n] = a[n-2] - a[n-6] is X(ω) = A(ω)e^2ω - A(ω)e^6ω.

x[n] = -u[-n-1]

The Fourier transform of a signal x[n] is given by X(ω) = ∑x[n]e^-jnω. In this case, the signal x[n] is -u[-n-1], so we can rewrite this as x[n] = -u[n+1]e^-j(n+1)ω. We can then use the Fourier transform formula to find the Fourier transform of the signal:

X(ω) = ∑(-u[n+1]e^-j(n+1)ω) e^-jnω

= -∑u[n+1]e^-jω

= -A(ω)e^-jω

Therefore, the Fourier transform of x[n] = -u[-n-1] is X(ω) = -A(ω)e^-jω.

x[n] 2* sin(n)ul-n)

The Fourier transform of a signal x[n] is given by X(ω) = ∑x[n]e^-jnω. In this case, the signal x[n] is 2*sin(n)u[-n], so we can rewrite this as x[n] = 2*sin(n)e^-jnω. We can then use the Fourier transform formula to find the Fourier transform of the signal:

X(ω) = ∑(2*sin(n)e^-jnω) e^-jnω

= 2∑sin(n)e^-jnω

= 2A(ω)sin(ω)

Therefore, the Fourier transform of x[n] = 2*sin(n)u[-n] is X(ω) = 2A(ω)sin(ω).

x[n] = (cos(n-1))

The Fourier transform of a signal x[n] is given by X(ω) = ∑x[n]e^-jnω. In this case, the signal x[n] is (cos(n-1)), so we can rewrite this as x[n] = cos(n-1)e^-j(n-1)ω. We can then use the Fourier transform formula to find the Fourier transform of the signal:

X(ω) = ∑(cos(n-1)e^-j(n-1)ω) e^-jnω

= ∑cos(n-1)e^-jω

= A(ω)cos(ω-1)

Therefore, the Fourier transform of x[n] = (cos(n-1)) is X(ω) = A(ω)cos(ω-1).

x[n] = sin(n) + cos(n)

The Fourier transform of a signal x[n] is given by X(ω) = ∑x[n]e^-jnω. In this case, the signal x[n] is sin(n) + cos(n), so we can rewrite this as x[n] = sin(n)e^-jnω + cos(n)e^-jnω. We can then use the Fourier transform formula to find the Fourier transform of the signal:

X(ω) = ∑(sin(n)e^-jnω + cos(n)e^-jnω) e^-jnω

= ∑sin(n)e^-jnω + ∑cos(n)e^-jnω

= A(ω) (sin(ω) + cos(ω))

Therefore, the Fourier transform of x[n] = sin(n) + cos(n) is X(ω) = A(ω) (sin(ω) + cos(ω)).

x[n] = sin(n) + cos(n)

The Fourier transform of a signal x[n] is given by X(ω) = ∑x[n]e^-jnω. In this case, the signal x[n] is sin(n) + cos(n), so we can rewrite this as x[n] = sin(n)e^-jnω + cos(n)e^-jnω. We can then use the Fourier transform formula to find the Fourier transform of the signal:

X(ω) = ∑(sin(n)e^-jnω + cos(n)e^-jnω) e^-jnω

= ∑sin(n)e^-jnω + ∑cos(n)e^-jnω

= A(ω) (sin(ω) + cos(ω))

Therefore, the Fourier transform of x[n] = sin(n) + cos(n) is X(ω) = A(ω) (sin(ω) + cos(ω)).

x[n] = x[n-6] + x[n+6]

The Fourier transform of a signal x[n] is given by X(ω) = ∑x[n]e^-jnω. In this case, the signal x[n] is x[n-6] + x[n+6], so we can rewrite this as x[n] = x[n]e^-6ω + x[n]e^6ω. We can then use the Fourier transform formula to find the Fourier transform of the signal:

X(ω) = ∑(x[n]e^-6ω + x[n]e^6ω) e^-jnω

= ∑x[n]e^-6ωe^-jnω + ∑x[n]e^6ωe^-jnω

= A(ω) (e^6ω + e^-6ω)

Therefore, the Fourier transform of x[n] = x[n-6] + x[n+6]

What is function?

A function from a set X to a set Y in mathematics assigns each element of X exactly one element of Y. The domain and codomain of the function are denoted by the sets X and Y, respectively. [Reference required]

The concept of function was first discussed by two Persian mathematicians named Al-Biruni and Sharaf al-Din al-Tusi. Functions were originally used to represent the idealised relationship between varying quantities and other variables. For example, time has an impact on a planet's position.

The concept was first developed at the end of the 17th century with the infinitesimal calculus, and up until the 19th century, the functions taken into account were differentiable.

What are Ball joints?

Ball joints are a component of a car's front suspension. The front suspension is a complex assembly of links, joints, bushings, and bearings that allow your front wheels to move independently up and down as well as turn left or right. Ball joints allow suspension movement, which increases tire contact with the road, resulting in better vehicle control and tire wear.

What are ball joints used for?

Ball joints are a critical component of the front suspension that connect and move various links. Ball joints, like the human hip joint, are made up of a ball and a socket.

which architectural element is common amongst both greek and etruscan architecture? rounded arches use of concrete atriums labyrinths save

Answers

The most common architectural element shared between Greek and Etruscan architecture is the use of rounded arches.

Rounded arches were used in both Greek and Etruscan architecture to create a sense of grandeur and grandiosity, as well as to support the weight of the structure. In Greek architecture, the use of arches was often seen in temples, colonnades, and other monumental structures, while in Etruscan architecture, arches were often used in tombs and other funerary structures.

Additionally, arches allowed for a greater degree of structural stability, as they were able to distribute weight better than straight walls or pillars. Furthermore, the use of rounded arches in both Greek and Etruscan architecture provided a stylistic unity, as the two cultures had many similarities in terms of their architectural styles.

Determine the absolute maximum shear stress developed in the beam.

Answers

In order to determine the absolute maximum shear stress developed in a beam, you will need to know the following information:

The beam's cross-sectional area: The amount of material that can withstand shear forces will be determined by this.

The shear stress that a beam can withstand before failing will depend on its material qualities.

The beam is being sheared by this force: The amount of shear stress that develops in the beam will depend on this.

The length of the beam will affect how much it deforms when a shear force is applied.

Using this knowledge, you can apply the calculation below to determine the absolute maximum shear stress that has been created in the beam:

Shear force / cross-sectional area equals shear stress.

Remember that the shear force is assumed to be distributed equally over the cross-section of the beam in this formula. The shear stress distribution across the beam may require a more involved analysis if the shear force is not distributed uniformly.
