"WebbGenerally, we calculate deflection by taking the double integral of the Bending Moment Equation means M (x) divided by the product of E and I (i.e. Young’s Modulus and Moment of Inertia). The unit of deflection, or displacement, will be a length unit and normally we measure it in a millimetre. " - Theoretical equations for point load

Webbw = Rate of loading in N/m RA = Reaction force at support A = w L/2 RB = Reaction force at support B = w L/2 θA = Slope at support A θB = Slope at support B Boundary condition We must be aware with the boundary conditions applicable in such a problem where beam will be simply supported and loaded with uniformly distributed load. Webbutmost importance. If a beam is supported at two points, and a load is applied anywhere on the beam, the resulting deflection can be mathematically estimated using the bending equation. Such estimation is based on certain assumptions which may not always be true. Due to this the actual results may vary from the theoretical results.
