Question

what are uses of drawing shear force and bending moment diagrams..please give best answer..

Answer 1

area of bm diagram give slope and that of sf diagram give deflection..

Answer 2

SFD and BMD are useful to obtain the span of the beam where the beam is bearing the maximum load and where it is resisting the maximum bending moment such that is it useful for design purpose. If we know those points,we can design according to the economical condition. How the beam is deflecting,...

Answer 3

those are used to find the deflections in the beam at any point throughout the beam.
