Determine the bending strain energy in the simply supported beam due to a uniform load w. Solve the problem two ways, (a) Apply Eq. 14-17. (b) The load w dx acting on the segment dx of the beam is displaced a distance y, where y = w(− x4 + 2Lx3−L3x)/(24ΕI), the equation of the elastic curve. Hence the internal strain energy in the differential segment dx of the beam is equal to the external work, i.e., dUi = (w dx)(−y). Integrate this equation to obtain the total strain energy in the beam. EI is constant.
