Q2 The internal bending moment in a beam with a cross sectional area shown in the figure is 500a in the direction shown. Nom Find: a) The centroid of the cross sectional area and, b) the maximum tensile and compressive normal stresses. Make a sketch showing the stress distribution A A -35 mm C2 100 mm C1 = ỹ 5 G0 Na m 25 mm B 50 25 50. mm 'mr mm

The simply supported beam in Figure below has a rectangular cross section 120 mm wide and 200 mm high: 1. Draw shear force and bending moment diagrams. 2. Compute the maximum bending stress in the beam. 10-kN/m 50m 25 m 100-m

A storage rack to hold the paper roll. Find force reactions and draw the shear and moment diagrams for the mandrel that extends half of the roll. Use singularity functions for this problem.
