What will be the relation between F and F’ if a force F is acted upon a uniform rod of cross-section A and a force F’ is acted upon a uniform rod of cross-section 4A, and the pressure on both the rods is the same?

Pressure (P) = F/A (on first rod)
Pressure (P’) = F’/4A (on second rod)
Given;
P = P’
F/A = F’/4A
F/F’ = 1/4.
