PSAD Refresher 52: Slab Supported by Three Rods

SITUATION: The rigid, homogeneous slab weighing 600 kN is supported by three rods of identical material and cross section. Before the slab was attached, the lower ends of the rods were at the same level. The three rods have diameter of 36 mm. 1. Calculate the stress (MPa) in rod A. A. 286 C. 181 B. 174 D. 234 2.
