When a drawer is pulled by only one of the handles, it tends to twist and rub as shown (highly exaggerated) in Fig. The weight of the drawer and its contents is 2 lb and is uniformly distributed. The coefficient of friction is 0.60 between the sides of the drawer and the sides of the dresser and 0.10 between the bottom of the drawer and the side rails the drawer rides on. Determine the minimum amount of force necessary to pull the drawer out. 0.75 in. 18 in 3 in. 24 in. 3 in. P

Assuming uniform pressure on the friction surface, show that the maximum torque that can be transmitted by the clutch is
Pls answer asap. Badly need it. Three identical blocks are placed on top of each other on a horizontal plane. Each block has a weight of 110 lb and the coefficient of friction between all surfaces is 0.25. If the upper most block is prevented from moving by a horizontal cable to a vertical wall, find the horizontal force that must be applied at the middle block without causing motion to impend.
