Question by furqan: How can I find point of zero shear force with an acentric point load on simply supported beam?
I needed to now how to calculate point of zero shear force (i.e., maximum bending moment)
Answer by SAGE
You have to be more clear but are you asking an eccentric point load on a simple loaded beam, where is the shear zero? If that is the case, you take the moment about any support which the sum would equal zero. You will get a reaction at the other support in the positive Y-direction. Now take the sum of forces to get the reaction in the Y direction at the support where you took the moment. Once you get both reaction, begin drawing the shear diagram. Reaction1 will be constant until it hits where the point load is, when it stretches over to the point load it will drop down at a magnitude of the point load in which, the shear will be negative and continue to the other support. The amount of drop at point should be equal to the positive upward force. Now where is the zero point shear load? There isnt any on a simply supported beam with a eccentric load. Even if the load was concentric, there would not be a zero shear load.
