8.18 Figure P8.18 a shows a uniform beam subject to a linearly in- creasing distributed load. The equation for the resulting elastic curve is (see Fig. P8.18b) WO -(-x+2L?x? Lx) (P8.18) 120 EIL 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. (P8.18) to determine the value of the maximum deflection. Use the following parameter values in your computation: L = 600 cm, E = 50,000 kN/cm, I = 30,000 cm*, and wo = 2.5 kN/cm
