Question

Two 160 mm * t cover plates are welded to two cahnnels 200 mm high to form the cross section of the beam shown in the figure. The moment of inertia of each channel about a horizontal axis through the centroid is 2.06*106mm4.

a)Determine the support reactions.

b)Draw the shear force and bending moment diagrams.

c)If the allowable bending stress of the beam is 255 MPa, find the required thickness t of the plates to safely support the load.
