Determine the maximum tensile and compressive stresses in

Question

Problem 1

The resultant internal moment acting on the cross section of the aluminum strut has a magnitude of M = 520 N-m and is directed as shown.

Determine the maximum tensile and compressive stresses in the strut.

Problem 2

The cantilever steel beam is subjected to the concentrated force of P = 600 N at the free end. The steel has a modulus of elasticity of 200 GPa. The moments of inertia about the principal axes of the cross section are determined as: I_y = 13.3 (10^-6)m⁴ = I_z = 28.8 (10^-6)m⁴.

Determine the neutral axis expression y(z), and sketch it over the cross section with at least one angle specified.
