A square crate of width 1 m is set on the end of a 10 m uniform plank. The plank is held horizontal by a rope on the other side of the plank. The mass of the crate and plank are 20 kg and 1p kg respectively. An angle of 30° is on the opposite side of the block. If a pivot is place 4 m from the left end of the plank what is thr tension of the rope? What is the normal force exertrd on the plank by the pivot?
