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...

A 5.0 kg box is on an incline tilted 45° from the horizontal. The coefficient of static friction between the box and the incline is 0.62. (a) Find the smallest force you have to push with (up along the incline) to keep the box from sliding down the incline. (b) Find the largest force you can push with before the box starts sliding UP the incline. Draw separate free-body diagrams for the two cases, and think carefully about which way...

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
