Problem 2 (Chapter 5): 8 A cantilever beam has a Z section of uniform thickness for which I, = 2 th, Iz th, 1 = 29th, 3 and Iz=-th. Determine the maximum bending stress in the beam subjected to a load P yz at its free end. y P C Z h If the only upper flange is subjected to a temperature raise, AT=100F, what is the induced stress of each component? Assuming, P=0 for this case. Let E and a be the modulus of elasticity and the coefficient of thermal expansion, respectively.
