The cylinder is uniform and has a mass of 5.00 kg. It is released from rest.a) Calculate the least coefficient of friction between the cylinder and the plane for which the cylinder will roll without slipping.b) Calculate the acceleration of the center of mass G of the cylinder if it rolls without slipping.

If the uniform cabinet has weight of 200 lb, and the coefficient of static friction between the cabinet and the ground is g = 0.14, determine the minimum force P that can make the cabinet slide. Please pay attention: the numbers may change since they are randomized. Your answer must include 1 place after the decimal point and proper unit. Take g = 32.2 ft/s². Your Answer: Answer P 4 ft units A -1 ft-1 ft- 3.5 ft B

Part A The arm is rotating at a rate of 0 = 4 rad/s when 6 = 3 rad/s and 0 = 180°. It is confined to move along the slotted path. Motion occurs in the horizontal plane.

I am not entirly sure what system this problem is decribing. what do the fbd's for this look like?

Please answer quickly. Thanks

The torsional spring has a stiffness of 20 N-m/rad and is undeflected when the 3-kg uniform slender bar is in an upright position. If the bar is released from rest in the horizontal position shown, find its angular velocity as it passes the vertical position.

A box with mass m = 2.75 kg rests on the top of a table. The coefficient of static friction between the box and the table is μs = 0.71 and the coefficient of kinetic friction is μk = 0.34. Write an expression for Fm the minimum force required to produce movement of the box on the top of the table. Solve numerically for the magnitude of the force Fm in Newtons. Write an expression for a, the box's acceleration, after it begins moving. (Assume the minimum force, Fm, continues to be applied.) Solve numerically for the acceleration, a in m/s2.

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 ls = 0.12, and the force Pis maximum so that the roller is about to slip, determine the angular acceleration of the roller (in rad/s²). 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.
