Two d mm*10 mm cover plates are welded to two UPN 200 channels 100 mm high to form the cross section of the compound beam shown in the figure. The moment of inertia of each channel about a horizontal axis through the centroid is 19.10*106
mm4.
a) Determine the support reactions.
b) Draw the shear force and bending moment diagrams.
c) If the allowable bending stress of the beam is 300 MPa, find the required width d of the plates to safely support the load.
