A crate with a weight of 100 N is sitting on top of a crate weighing 200 N. The rope that joints the crates passes around a frictionless pulley at A and a fixed drum at B
A crate with a weight of 100 N is sitting on top of a crate weighing 200 N. The rope that joints the crates passes around a frictionless pulley at A and a fixed drum at B. If the coefficient of friction is H 0.30 at all surfaces, determine the minimum force P required to start the 200 N crate moving.

Suppose you have to move a heavy crate of weight 875 N by sliding it along a horizontal concrete floor. You push the crate to the right with a horizontal force of magnitude 300 N, but friction prevents the crate from sliding. What is the magnitude Fp of the minimum force you need to exert on the crate to make it start sliding along the floor? Let the coefficient of static friction μs between the crate and the floor be...
