A clown of mass Mc= 100kg stands still at the far right end of a plank of uniform density, mass Mp= 60kg, and length L= 4m that is supported by a frictionless hinge L/4 from the right side of the plank, and it is in contact with a vertical pole hanging from the ceiling at a point that is L/4 from the left side of the plank. a) Draw an "extended" free body diagram indicating where each of the forces acts on the plank. b) What is the direction and magnitude of the force from the hinge on the plank? c) What is the magnitude of the force from the pole pushing down on the plank?
