Chapter 15, Problem 15.31P

For Problems 15.31 through 15.43, use the moment-area method.

15.31 A steel bar is $\text{3}$ in. wide and $\text{1}$ in, thick. It is used as a $\text{1}0$ -ft-long simply supported beam. Bending is about the weak axis. The beam supports two concentrated loads of $\text{12}0$ lb each spaced $\text{4}$ ft apart and placed $\text{3}$ ft from each end. Calculate the maximum deflection and the deflection at one of the loads.
