Answer:
f = 628.32 lb
t = 2513.28 lb-inc
Explanation:
given data:
θ = 45°
outside radius = 6 inch
inside radius = 4 inch
coefficient of friction = 0.4
max pressure = 100 psi
a) determine force required for applying one pad
f = ![\frac{\theta }{360}* 2\pi *p_{max}*r_{i}(r_{o}-r_{i})](https://tex.z-dn.net/?f=%20%5Cfrac%7B%5Ctheta%20%7D%7B360%7D%2A%202%5Cpi%20%2Ap_%7Bmax%7D%2Ar_%7Bi%7D%28r_%7Bo%7D-r_%7Bi%7D%29)
f = ![\frac{45 }{360}* 2\pi *100*4(6-4)](https://tex.z-dn.net/?f=%20%5Cfrac%7B45%20%7D%7B360%7D%2A%202%5Cpi%20%2A100%2A4%286-4%29)
f = 628.32 lb
b) torque capacity (t)
t = ![\mu *f*r_{average}^{}](https://tex.z-dn.net/?f=%5Cmu%20%2Af%2Ar_%7Baverage%7D%5E%7B%7D)
t = 0.4 *628.32*5
torque = 1256.64 lb-inc
for both pad = 2 * 1256.64 =2513.28 lb-inc
Answer:
W = 166.35 KJ
Explanation:
P₁ = 600 KPa
V₁ = 0.4 m³
V₂ = 0.2 m³
T = 300 K
W = ?
We can find the solution from the standard relation for work in an isothermal process
W = -n*R*T*Ln (Vf / Vi)
We know that
n*R*T = P*V ⇒ P₁*V₁ = P₂*V₂ = n*R*T = 600 *0.4 = 240
Now, we use the equation
W = -n*R*T*Ln (Vf / Vi) = - P₁*V₁*Ln (Vf / Vi)
⇒ W = -240*Ln (0.2 / 0.4) = 166.35 KJ
Answer:
1) This is because too much fuel is needed to get a payload from the surface to orbital altitude an accelerated to orbital speed.
2) This is because space travel present extreme environment that affect machines operations and survival.

Remove whatever is holding the old filter in place and remove it. Put the new filter on in the same position as the old filter. Replace whatever holds the filter in place, and make sure it's secure. Replace the fuse for the fuel pump in the fuse box.
Answer:
Slopping or slanting roofs are found in houses where there are snow or rain, because it helps the water or the snow to skid down easily. It minimizes the chances of waterlogging because water cannot rest on the roof surface for long.
