Structures under Combined Loading

Example: (continued) Stresses on elements at A and at B

For element A:

σ_x = (M_z)c/I + R/A = (1500)(0.95)/(0.3) + 150/0.8 = 4938 psi

τ_zx = (M_x)r/ J = (2000)(0.95)/(0.6) = 3167 psi

For element B :

σ_y = - (M_y)c/I + R/A = - (900)(0.95)/(0.3) + 150/0.8 = - 2663 psi

τ_xy = (M_x)r/ J = (2000)(0.95)/(0.6) = 3167 psi
