What this calculator does
Overhanging Beam Bending Moment and Shear Calculator: Applies the standard mechanics-of-materials relationship for this load case so a student can see how the stress, strain or deflection follows from the geometry and the load.
What your result means
The headline figure tells you how hard the material is being worked, or how much it moves, under the load you entered. Compare it with the allowable value for your material and required factor of safety.
Formula and working
M_overhang = P·a (at support); V = P
- 1
Collect the inputs
Point load at free end = 5,000 N; Overhang length = 1 m; Span between supports = 4 m
- 2
Apply the formula
M_overhang = P·a (at support); V = P
- 3
Result
Max bending moment at support = 5,000 N·m

- • This is an educational estimate for learning and checking, not a design deliverable.
- • Real design must follow the governing code or standard for your jurisdiction and be reviewed and signed off by a qualified engineer.
- • Safety factors, load combinations and material certification are the responsibility of the designer, not of this page.
Important limitation
This is an educational estimate based only on the values and formula shown. Verify current rates, rules, units, and professional standards before relying on the result. It is not personalized financial or investment advice.
