The coefficient of static friction between the block A and the cart B is μs. If the assembly is released from rest on the inclined plane, determine the smallest value of μs that will prevent the block from sliding on the cart.

Two blocks A and B have a weight of 11 lb and 6 lb , respectively. They are resting on the incline for which the coefficients of static friction are μA = 0.16 and μB = 0.23. Determine the angle θ which will cause motion of one of the blocks. What is the friction force under each of the blocks when this occurs? The spring has a stiffness of k = 2 lb/ft and is originally unstretched. Determine the smallest angle θ which will cause motion of one of the blocks. Determine is the friction force under the block A at this angle. Determine is the friction force under the block B at this angle.

The 2-kg spool S fits loosely on the inclined rod for which the coefficient of static friction is μ = 0.28. (a)  If the spool is located 0.25 m from A, determine the maximum constant speed the spool can have so that it does not slip up the rod. Express your answer to three significant figures and include the appropriate units.

Under the man's pushing force P= 34.8 lb, the uniform cabinet is sliding on the ground with a constant acceleration of a. If the uniform cabinet has weight of 150 lb, and the coefficient of kinetic friction between the cabinet and the ground is μk = 0.12, determine the normal force reaction under leg A. Please pay attention: the numbers may change since they are randomized. Your answer must include 2 places after the decimal point and proper unit.
