Beam Deflection
Beam Deflection
(OP)
Hi,
I am trying to calculate the deflection of a horizontal cantilevered beam of a length l that has two loads on it at unequal distances. The loads are the same so P1 = P2. The distances a and b are from x = 0. I cannot find an equation to suit and when I try to derive it using Castiglianos Theorem I get unreasonable answers. Any help would be appreciated.
Thanks

When you find the equations, which should be in most structural texts, there should be 4 different equations: deflection at tip, deflection at load, deflection at any point between load and tip, deflection at any point between load and support. So you can compute the deflection at any desired point on the beam. Do it for both loads, and as Ussuri and apsix have advised, use principle of superposition, or as I said, add them up.
