Question

Two smooth spheres, each of radius r and weight Q rest in the vertical walls, the distance between them is b. Find the pressure exerted on the walls and floor at the points contact A, B and D. r=254mm, b=914mm, Q=445N.

Answer 1

Area of contact is more or less a point that means area tends to 0 and pressure tends to infinity on floors. On vertical walls there's no force exerted even though there's a point of contact so pressure is 0.
