SFD and BMD for different beams

Question

Accepted Answer

SFD and BMD are diagrams used to show the variation of shear force and bending moment along the length of a beam.

SFD (Shear Force Diagram) shows the variation of shear force along the length of a beam.
BMD (Bending Moment Diagram) shows the variation of bending moment along the length of a beam.
SFD and BMD are essential for analyzing the internal forces in a beam and designing appropriate supports and reinforcements.
Example: For a simply supported beam with a point load at the center, the SFD will show a constant positive shear force on one side of the load and a constant negative shear force on the other side, while the BMD will show a linearly increasing bending moment towards the center.
Example: For a cantilever beam with a uniformly distributed load, the SFD will show a linearly decreasing shear force from the fixed end to the free end, while the BMD will show a parabolic bending moment distribution.
