Question: A straight prismatic beam AD has a rectangular cross - section with width b and herght n . Its totar length is 4 l .

A straight prismatic beam AD has a rectangular cross-section with width b and herght n. Its totar length is 4l. Its Young's modulus is E. The beam is subjected to distributed load q per unit length, as shown in the figure below.
(1) Please use the energy method to determine the deflection, v, at x=l.
(2) Please use the energy method to determine the slope of the deflection curve, v', at x=31.
