uniformly distributed load is Ely = 8x^240x, then the beam length is

A simply supported I-beam is loaded with a distributed load, as shown. The deflection, y, of the center line of the beam as a function of the .position, x, is given by the equation: where L-4 m is the length, E=5 GPa is the elastic modulus, I=60 x 10^(-6) m^4 is the moment of inertia, and wo=20 kN/m. Find the position x where the deflection of the beam is maximum in meters. Express your answer in meters with six decimal digits after decimal point. Wox y = 360LEIL*- 10L2x² + 3x+)
