- For concentrated or point load, SFD is rectangular (uniform) and BMD is triangular (linear).
- For uniformly distributed load, SFD is triangular and BMD is parabolic.
- For uniformly varying load, SFD will be parabolic and BMD will be cubic.
- If the algebraic sum of moments on the beam is zero and no other forces are acting then reactions are zero and SFD is a straight line.
- If there is a vertical ordinate or sudden jump in a BMD, it indicates concentrated moment at that point whose magnitude is equals to length of the ordinate.
- At fixed end, bending moment is always zero, until an concentrated moment not there.
