A steel beam (E = 30*10^3 ksi) and an aluminum (E = 10*10^3 ksi) beam are attached to an instrumentation box as shown. Both beams have a thickness of 0.30 inches and a width into the plane of the paper of 1.5 inches. Vibration measurements from the instrumentation box indicate a sinusoidal displacement with a maximum displacement Amax = 0.20 inches and a minimum displacement Amin = -0.2 inches. The stress concentration at both fixed supports is negligible. If AISI cold rolled 1030 steel (Sut=76 ksi) is used, will the steel beam have an infinite fatigue life? (ignore instrumentation box length) ta 10 in aluminum steel instrumentation box 70

A steel beam (E = 30*10^3 ksi) and an aluminum (E = 10*10^3 ksi) beam are attached to an instrumentation box as shown. Both beams have a thickness of 0.30 inches and a width into the plane of the paper of 1.5 inches. Vibration measurements from the instrumentation box indicate a sinusoidal displacement with a maximum displacement max = 0.20 inches and a minimum displacement min = -0.2 inches. The stress concentration at both fixed supports is negligible. If AlSI cold rolled 1030 steel (Sut =76 ksi) is used, will the steel beam have an infinite fatigue life?
