Bending moment formula calculates the internal bending moment in a beam or structure.

• Bending moment formula is M = F * d

• M is the bending moment, F is the force applied, and d is the distance from the force to the point of interest

• Bending moment can be positive or negative depending on the direction of the force and the orientation of the beam

• Bending moment is an important factor in designing and analyzing structures
