About Reaction Force Calculation

Reaction forces are the forces exerted by supports to balance external loads on a structure. This calculator helps determine these forces for different beam configurations and load types, which is essential for structural analysis and design.

How to Use This Calculator

Select your beam type (simply supported, cantilever, or fixed-fixed)
Enter the beam length
Choose the load type (point load, UDL, or triangular load)
Enter the load parameters
Click “Calculate Reaction Forces”

Common Applications

Structural engineering design
Civil engineering projects
Mechanical system analysis
Academic studies and homework
Construction planning
