DQuestion 17 5 pts The cross section of a composite beam made of aluminum and steel is shown in the figure. The moduli of elasticity are Ea 75 GPa and Es 200 GPa. Under the action of a bending moment that produces a maximum stress of 50 MPa in the aluminum, what is the maximum stress in the steel (MPa)? 30 mm 40 mm Aluminunm Steel 80 mm 0
15 Section 5, Problem 15 (25 pts.). A member is loaded by forces a, cand d as shown. The member is a hollow member with an outer radius of ro and a wall thickness of t. The member is fixed at ground level where points Fand G occur. Determine: a) the normal and shear stress at point F. b) the normal and shear stress point 02:46:29 Forces: a = 30 (k),c=16 (k), and -17 (K) Dimensions: e = 32 (in.),...
