Problem B $(25$ points$)$

For each of the beams loaded as shown below, $($a$)$ draw the shear and bending$-$moment diagrams, $($b$)$ determine the magnitude and location of the maximum absolute values of the shear and bending moment. Assume that the weight of the beam is negligible. PLZ DRAW THE SHEAR AND BENDING
