Solve Prob. 4€“13 using singularity functions. Since the beam is symmetric, only write the equation for half the beam and use the slope at the beam center as a boundary condition. Use statics to determine the reactions.
Prob. 4€“13, A rectangular steel bar supports the two overhanging loads shown in the figure.

Using superposition, find the deflection at the ends and at thecenter.
