Solve Prob. 4–21 using singularity functions to determine the deflection equation of the beam. Use statics to determine the reactions.

Prob. 4–21, Consider the uniformly loaded simply supported steel beam with an overhang as shown. The second-area moment of the beam is I = 0.05 in 4. Use superposition (with Table A–9 and the results of Prob. 4–20) to determine the reactions and the deflection equations of the beam.

Plot the deflections.
