The simple beam \( A B \) supports a uniform load of intensity \( q=10 \mathrm{lb} / \) in. acting over one-half of the span and a concentrated load \( \mathrm{P}=80 \mathrm{lb} \) acting at midspan (see figure below). Draw the shear-force and bending-moment diagrams for this beam and find the maximum shear force and bending moment. (20 points)
