Problem 4: The rigid "I-shaped" beam is held in place by two rods as pictured below. The rods have Young's Modulus F, coefficient of thermal expansion o and cross-sectional area A. At a temperature 7, the rods ure free of stress. If the temperature is changed from this value by an amount 47, determine the stress developed in the rods. L 2L
