Question

Two circular rods support the 3800 lb weight of a space heater in a warehouse. Each rod has a diameter of 0. 375 in and carries 1/2 of the total load. Compute the stress in the rods

Answer 1

Force carried by each rod, F = 3800 / 2 = 1900 lb

Cross-sectional area of each rod, A = pi ( d^2) / 4

A = pi * 0.375 * 0.375 / 4 = 0.1104 in^2

Stress in each rod = F / A = 1900 / 0.1104

= 17.21 * 1000 psi

= 17.21 ksi
