5.13 Figure PS.13a shows a uniform beam subject to a lin-
early increasing distributed load. The equation for the result-
ing elastic curve is (see Fig. P5.13b)
(P5.13)
Use bisection to determine the point of maximum deflection
(that is, the value of x where dy/dx = 0). Then substitute this
value into Eq. (P5.13) to determine the value of the maximum
deflection. Use the following parameter values in your com-
putation: L = 600 cm. E= 50,000 kN/cm', /= 30,000 cm*,
and wo = 25 kN/cm
