In short, you would simple move along the beam plotting the vertical force and how it changes along the member. Engineering Calculators you're better off solving the problem numerically with one of our finite element analysis tools. In structural engineering, deflection is the degree to which a part of a structural element is displaced under a load (because it deforms).It may refer to an angle or a distance. The plate is flat, of uniform thickness, and of homogeneous isotropic material; the thickness is not more than about one quarterof the least transverse dimension, and the maximum deflection, all forces, loads and reactions are normal to the plane of the plate; and, the plate is nowhere stressed beyond the elastic limit.
