Two forces P can be applied separately or at the same time to a plate that is welded to a solid circular bar of radius r. Determine the largest compressive stress in the circular bar, (a) when both forces are applied, (b) when only one of the forces is applied.

Answer:

A) 2P/(¶r^2)

B) p/(¶r^2)

Explanation:

Force = P

Radius = r

Area on which force acts = ¶r^2

If both forces are applied, total stress will be

S = 2P/(¶r^2)

When only one of the force is applied

S = p/(¶r^2)
