A uniform plank with length L and mass M rests on the ground andagainst a frictionless roller at the top of a wall of height h.Consider that h remarkably is smaller than L. The plank remains inequilibrium when the angle between the plank and ground surface isgreater than or equal to 𝜃0. Find
A) the normal forces applied on the plank from the wall,
B) the normal forces applied on the plank from the ground,and
C) the coefficient of static friction.
