[ANSWERED] 1. For the beam loaded as shown in Figure P4–15, determine the free-end deflection and the reactions

1. For the beam loaded as shown in Figure P4–15, determine the free-end deflection and the reactions and draw the shear force and bending moment diagrams. Assume EI constant throughout the beam.
2. Using the concept of work equivalence, determine the nodal forces and moments (called equivalent nodal forces) used to replace the linearly varying distributed load shown in Figure P4–16.
