To find the deflection as a function of location, due to a uniform load , the ordinary differential equation that needs to be solved is (1) where. is the length of the beam, is the Young’s modulus of the beam, and . is the second moment of area of the cross-section of the beam. Two conditions are needed to solve the problem, and those are (2a,b)
