At 65 degrees Fahrenheit, a composite material has the specified dimension. The steel rod is cooled until it slides into the link without resistance. The entire assembly is then heated to a temperature of 100 degrees Fahrenheit. Determine the following: a. The final normal stress in the steel rod b. The final length of the steel rod. EBR = 15 106 psi BR = 10.4 10-6/F EST = 29 106 psi ST = 6.5 x 10-6/F Brass A 0.005 in 10 in Steel A Section A-A 2 in 1.5 in 1.5 in 1.25-in diameter
