determine the acceleration of each block.

Determine the minimum force P to prevent the 30-kg rod AB from sliding. The contact surface at B is smooth, whereas the coefficient of static friction between the rod and the wall at A is = 0. - 4m -

The man pushes on the roller with force P through a handle that connects to the central axle of the roller. If the coefficient of static friction between the 43-lb roller and the floor is Hs = 0.21, and the force Pis maximum so that the roller is about to slip, determine the angular acceleration of the roller (in rad/s?). Assume the roller to be a uniform cylinder. Please pay attention: the numbers may change since they are randomized. Your answer must include 2 places after the decimal point, and proper unit. Take g = 32.2 ft/s?. 1.5 ft 30°

8 Determine the minimum horizontal force P required to hold the crate from sliding down the plane. The crate has a mass of 100 kg and the coefficient of static friction between the crate and the plane is µ; =0.25 P 30° 9..Determine the minimum force P required to push the crate up the plane. The crate has a mass of 50 kg and the coefficient of static friction between the crate and the plane is us =0.25.
