The problems for Section 10.4 are to be solved by the method of superposition. All beams have constant flexural rigidity EI unless otherwise stated. When drawing shear-force and bending-moment diagrams, be sure to label all critical ordinates, including maximum and minimum values.
A propped cantilever beam AB of length L carries a concentrated load P acting at the position shown in the figure.
Determine the reactions RA, RB, and MA for this beam. Also, draw the shear-force and bending-moment diagrams, labeling all critical ordinates.
