Data are as follows: P = 6.2 kN, L = 3.2 m, d = 1.25 m, b = 80 mm, t = 25 mm, h = 120 mm, and h1 = 90 mm. (1) Locate the position of the neutral axis in the cross section as shown in Fig.3-a. ((2) Determine the maximum tensile stress σt,max and maximum compressive stress σc,max due to the load P acting on the simple beam AB, if the cross section has the moment of inertial about the neutral axis is IZ = 5.88×10-6 m4.

A freight-car axle AB is loaded approximately as shown in Fig.3-b, with the forces P representing the car loads and the forces R representing the rail loads. The diameter of the axle is d = 82 mm, the distance between centers of the rails is L, and the distance between the forces P and R is b = 220 mm. Please calculate the maximum bending stress σmax in the axle if P = 50 kN.
