When solving the problems for Section 4.5, draw the shear-force
and bending-moment diagrams approximately to scale and label all
critical ordinates, including the maximum and minimum values.
Probs. 4.5-1 through 4.5-10 are symbolic problems and
Probs. 4.5-11 through 4.5-24 are numerical problems. The remaining
problems (4.5-25 through 4.5-40) involve specialized topics, such
as optimization, beams with hinges, and moving loads. P a P a A B Problem 4.5-1 Draw the shear-force and bending-moment diagrams for
a simple beam AB supporting two equal concentrated loads P (see figure).
L Solution 4.5-1 Simple beam Problem 4.5-2 A simple beam AB is subjected to a counterclockwise
couple of moment M0 acting at distance a from the left-hand support
Draw the shear-force and bending-moment diagrams for this beam. M0
