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.

Evaluate if the 2-kg crate is in equilibrium or is sliding knowing that force P=60 N. If it is sliding make sure to mention if it will slide uphill or downhill. In any case evaluate : a) the actual friction acting on the crate. b) Where the normal force is applied (will it tilt)? Other data: alpha=a= 27°; theta = 0 = 37°; us = 0.30; Uk = 0.25; a = b = 40 cm; c= 20 cm
