1. For the beam shown in Figure P4–3, determine the rotation
at pin support A and the rotation and displacement under the load P. Determine
the reactions. Draw the shear force and bending moment diagrams. Let EI be
constant throughout the beam.
2. For the cantilever beam subjected to the free-end load P
shown in Figure P4–4, determine the maximum deflection and the reactions. Let
EI be constant throughout the beam.
