Solve Prob. 4€“19 using singularity functions to determine the deflection equation of the beam. Use statics to determine the reactions.
Prob. 4€“19, Using the results of Prob 4€“18, use superposition to determine the deflection equations for the three regions of the beam shown.

Prob 4€“18, Calculating beam deflections using superposition is quite convenient provided you have a comprehensive table to refer to. Because of space limitations, this book provides a table that covers a great deal of applications, but not all possibilities. Problem 4€“19 is not directly solvable from Table A€“9, but with the addition of the results of this problem, it is. For the beam shown, using statics and double integration, showthat
