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. WebbL2/4= 2yR. y = L2/8R. Let us recall the bending equation and we can write as mentioned here. M/I = E/R. R = (E x I)/M. Now we will use the above value of radius R in equation of deflection and we will have the formula or expression for the deflection of the beam y as mentioned here.
