What Is a Beam Load Calculator?
A Beam Load Calculator is a structural analysis tool that determines how a beam behaves under different types of loads. It calculates:
- Reaction forces at supports (Left and Right)
- Maximum shear force
- Maximum bending moment
It supports two main load types:
- Uniform Distributed Load (UDL)
- Point Load (centered load)
By entering beam length and load values, users can instantly get engineering results without manual calculations.
