For the given section, (a) determine the moment of inertia about z & y-axes. (b) if the section is subjected to Mz= 10 kN-m and My-25 kN-m, determine the maximum tensile bending stress and find its location on the section (use the notation of A, B,C, and D). 15 mm 50 mm 2 + 50 mm C 15 mm 10 mm 100 mm 8

Determine the reaction forces R1 and R2 and show the shear and bending moment diagram. Data: Point load (left-most) = 90.126 N Uniformly distributed load (80mm to 260mm) = 0.14444 N/mm Uniformly distributed load (160mm to 180mm) = 6.5 N/mm

2. A 150 kip-ft (negative 150 kip-feet) moment is acting at the centroid of the cross section shown on the next page. Determine the bending stress-in psi - at a point that is located (a) at the top surface of the cross section. (b) 3 inches down from the top surface of the cross section. (c) 12 inches up from the bottom surface of the cross section. (d) 3 inches up from the bottom surface of the cross section. (e) at the bottom surface of the cross section. M

Determine the bending stress at point A of the beam, and the orientation of the neutral axis. Using the method in Appendix A, the principal moments of inertia of the crosssection are Iz = 8.828 in4 and Iy = 2.295 in4, where z and y' are the principal axes. Solve the problem using Eq.
