1. The problem statement, all variables and given/known data Apply the principle of superposition to a beam to calculate or show beam deflection. 2. Relevant equations Maximum Deflection. (WL^3) / (48EI) Equation for possition two, when possition two is 3/4 or 1/4 of the total beam lengh (Cant figure out the above) 3. The attempt at a solution I think i need to sum the two figure, however, cant get a figure for point two. Think i need an equation to calculate deflection at a given point?
