Question

6.Beam AB, having a size of 2kN/m, has two distribution loads of uniform size and two concentric loads on P and Q. The value of vertical stress due to bending acting on the underside of a beam is known as -56.9MPa in A and -29.9MPa in C. (1) Draw a line of foreshafts and bending moments. Also determine the size of the maximum shear stress acting on the right side section of the A point.

7.In Figure P7-7 calculate the maximum value of a constant distribution load w. Beams are made of materials with +80MPa tensile strength and -130MPa compressive strength. The dimensions of the figure are mm.
