What variation in cross feeding is usually applied for grinding harder workpieces of the same material?

The minimum required diameter should be 5 mm for each rod.

In physics, stress describes the force acting on a material's unit area. A specific body can become deformed under stress. Strain is the term for the impact that stress has on the body. To restore an object to its original form and size, an opposing force known as a restoring force is produced inside the object. The symbol "σ" stands for stress, which is a tangible quantity. N/m2 is the stress unit in the SI system.

Strength is an object's capacity to withstand the applied stress to the fullest extent possible. Physics distinguishes between two types of stress: Tangential or Shearing Stress and Normal Stress based on the direction of the deforming forces that act on a body.

Answer:

The answer is below

Explanation:

Given that:

Diameter (D) = 0.03 mm = 0.00003 m, length (L) = 2.4 mm = 0.0024 m, longitudinal tensile strength \((\sigma_{cd})=630\ MPa = 630*10^6\ Pa\), Fracture strength

\((\sigma_f)=5100\ MPa=5100*10^6\ Pa,fiber-matrix\ stres(\sigma_m)=17.5\ MPa=17.5*10^6\ Pa,matrix\ strength=\tau_c=17\ MPa=17 *10^6\ Pa\)

a) The critical length (\(L_c\)) is given by:

\(L_c=\sigma_f*(\frac{D}{2*\tau_c} )=5100*10^6*\frac{0.00003}{2*17*10^6}=0.0045\ m=4.5\ mm\)

The critical length (4.5 mm) is greater than the given length, hence th composite can be produced.

b) The volume fraction (Vf) is gotten from the formula:

\(\sigma_{cd}=\frac{L*\tau_c}{D}*V_f+\sigma_m(1-V_f)\\\\V_f=\frac{\sigma_{cd}-\sigma_{m}}{\frac{L*\tau_c}{D}-\sigma_{m}} \\\\Substituting:\\\\V_f=\frac{630*10^6-17.5*10^6}{\frac{0.0024*17*10^6}{0.00003} -17.5*10^6} \\\\V_f=0.456\)

The meole fraction of acetone in the outlet liquid is \(x_1 = 0.0072\)

Explanation:

1.

The schematic diagram to represent this process is shown in the diagram attached below:

2.

the mole fraction of acetone in the outlet liquid is determined as follows:

solute from Basis Gas flow rate \(G_s = 10(1-0.012) =9.88 kmol/hr\)

Let the entering mole be :\(y_1 = 1.2\) % = 0.012

\(y_1 =(\dfrac{y_1}{1-y_1})\)

\(y_1 =(\dfrac{0.012}{1-0.012})\)

\(y_1 =0.012\)

Let the outlet gas concentration be \(y_2\) = 0.1% = 0.001

\(y_2 = 0.001\)

Thus; the mole fraction of acetone in the outlet liquid is:

\(G_s y_1 + L_s x_2 = y_2 L_y + L_s x_1\)

\(9.88(0.012-0.001)=15*x_1\)

\(9.88(0.011) = 15x_1\)

\(x_1 = \dfrac{0.10868}{15}\)

\(x_1 = 0.0072\)

The mole fraction of acetone in the outlet liquid is \(x_1 = 0.0072\)

Section Key Terms

kinetic friction static friction

Static Friction and Kinetic Friction

Recall from the previous chapter that friction is a force that opposes motion, and is around us all the time. Friction allows us to move, which you have discovered if you have ever tried to walk on ice.

There are different types of friction—kinetic and static. Kinetic friction acts on an object in motion, while static friction acts on an object or system at rest. The maximum static friction is usually greater than the kinetic friction between the objects.

Imagine, for example, trying to slide a heavy crate across a concrete floor. You may push harder and harder on the crate and not move it at all. This means that the static friction responds to what you do—it increases to be equal to and in the opposite direction of your push. But if you finally push hard enough, the crate seems to slip suddenly and starts to move. Once in motion, it is easier to keep it in motion than it was to get it started because the kinetic friction force is less than the static friction force. If you were to add mass to the crate, (for example, by placing a box on top of it) you would need to push even harder to get it started and also to keep it moving. If, on the other hand, you oiled the concrete you would find it easier to get the crate started and keep it going.

Figure 5.33 shows how friction occurs at the interface between two objects. Magnifying these surfaces shows that they are rough on the microscopic level. So when you push to get an object moving (in this case, a crate), you must raise the object until it can skip along with just the tips of the surface hitting, break off the points, or do both. The harder the surfaces are pushed together (such as if another box is placed on the crate), the more force is needed to move them.

Both Technician A and Technician B are correct about active steering systems. Active steering systems are designed to improve vehicle stability and maneuverability by providing a more responsive and adaptive steering experience.

Technician A's statement about active steering turning the wheels more or less sharply than commanded by the steering wheel is correct. Active steering systems use sensors and algorithms to detect changes in the vehicle's speed, direction, and other parameters to adjust the steering angle accordingly. This can help the vehicle maintain its course and stay stable even under challenging road conditions.

Technician B's statement about the system allowing for a variable steering ratio dependent on vehicle speed is also correct. Active steering systems can adjust the steering ratio based on the vehicle's speed, allowing for smoother and more precise handling at high speeds and more agile and responsive turning at low speeds.

Answer:

The wind force on the screen is approximately 5,341.5936 \(lb_f\)

Explanation:

The speed of the wind, v = 36 mph

The width of the outdoor movie, w = 70 ft. wide

The height of the outdoor movie, h = 20 ft. tall

The drag coefficient, Cd = 1.15

We have;

\(C_d = \dfrac{F}{\dfrac{\rho \cdot v^2 \cdot A}{2} }\)

From which we have;

The wind force, F = 0.00256·\(C_d\)·v²·A

Where;

A = The cross sectional area of the rectangular outdoor movie screen, A = w × h

∴ A = 70 ft. × 20 ft. = 1,400 ft.²

The wind force, F = 0.00256 × 1.15 × (36 mph)² × 1,400 ft.² = 5,341.5936 \(lb_f\)

The wind force on the screen, F = 5,341.5936 \(lb_f\).

The wind force on the outdoor movie screen is;

F = 23437.26 N

We are given;

Wind speed; v = 36 mph = 16.0934 m/s

Width of screen; w = 70 ft = 21.336 m

Height of screen; h = 20 ft = 6.096 m

Drag coefficient; Cd = 1.15

Now formula for the drag force is;

F = ½•C_d•ρ•A•v²

Where;

F is drag force

C_d is drag coefficient

ρ is density of object

v is speed of object

A is area

Let us use density as 1.21 kg/m³

Area; A = wh = (21.336 × 6.096)

Thus;

F = ½ × 1.15 × 1.21 × (21.336 × 6.096) × 16.0934²

Glomerular filtration rate (GFR) refers to the amount of blood filtered per minute by the glomeruli in the kidneys.

GFR is an important measure of kidney function and is often estimated based on creatinine clearance results. In this case, a 30-year-old patient with a creatinine clearance result of 120 ml/min, the nurse would estimate the GFR to be approximately 120 ml/min as well.This is because creatinine clearance is a good indicator of GFR. The kidneys filter creatinine from the blood, and the amount of creatinine that is excreted in the urine is proportional to the amount that is filtered by the kidneys. Therefore, creatinine clearance is an indirect measure of GFR. A creatinine clearance result of 120 ml/min suggests that the kidneys are functioning well and are able to filter a normal amount of blood per minute. This would correspond to a GFR of approximately 120 ml/min as well.

a. The mass will have a velocity equal to half its maximum velocity at a distance of 0.707x0 from equilibrium.

b. The mass will have an acceleration equal to half its maximum acceleration at a distance of 0.5x0 from equilibrium.

The motion of a mass attached to a spring is described by the equation:

x = A cos(ωt + φ)

where x is the displacement from equilibrium, A is the amplitude of the motion, ω is the angular frequency (ω = sqrt(k/m) where k is the spring constant and m is the mass), t is time, and φ is the phase angle.

The maximum velocity and acceleration occur at the equilibrium position (x=0) and are given by:

v_max = Aω

a_max = Aω^2

To find the distance from equilibrium where the velocity is half its maximum value, we can solve for the displacement x when v = v_max/2:

v = -Aω sin(ωt + φ) = v_max/2

sin(ωt + φ) = -1/2

ωt + φ = -π/6 or 7π/6

Substituting ω = sqrt(k/m) and t = T/4 (where T is the period of the motion) gives:

sqrt(k/m)T/4 + φ = -π/6 or 7π/6

Solving for A cos(φ) (which is the displacement from equilibrium) gives:

A cos(φ) = ±(sqrt(3)/2)A

Therefore, the distance from equilibrium where the velocity is half its maximum value is 0.707x0.

To find the distance from equilibrium where the acceleration is half its maximum value, we can solve for the displacement x when a = a_max/2:

a = -Aω^2 cos(ωt + φ) = a_max/2

cos(ωt + φ) = -1/2

ωt + φ = ±2π/3

Substituting ω = sqrt(k/m) and t = T/3 gives:

sqrt(k/m)T/3 + φ = ±2π/3

Solving for A cos(φ) gives:

A cos(φ) = ±0.5x0

Therefore, the distance from equilibrium where the acceleration is half its maximum value is 0.5x0.
