Can I use the Beam Calculator for a cantilever beam with a point load at the free end?

Yes, the tool supports cantilever beams and allows you to apply point forces at any location along the beam, including the free end, to model that loading case.

What units does the Beam Calculator use for deflection results?

Results can be displayed in either US customary units or SI units, which you select from the Display Units menu before running the calculation.

How do I interpret the bending moment and shear force diagrams produced by the calculator?

The diagrams show the variation of bending moment and shear along the beam length; positive values typically indicate sagging moment and upward shear, while the magnitudes help identify maximum stress points and deflection zones.

About this tool

What Beam Deflection Calculator does

The Beam Calculator on MechaniCalc computes reactions, shear forces, bending moments, slopes, and deflections for straight beams. Users configure the beam’s length, material properties, and cross-sectional geometry, then apply point forces, distributed loads, and support constraints to model simply supported or cantilever configurations. The output includes detailed results for stress, deflection, and deformation, with options to display units in US or SI systems. While the tool is free to use, the site notes limited free access without a paid plan for basic functionality. It also references a separate 2D FEA calculator for more complex structures.

Step by step

How to use the MechaniCalc Beam Deflection Calculator

1
Open the Beam Calculator on MechaniCalc and input the beam Length, select Material, and define Cross Section details including Inertia and Elastic Modulus.
2
Add Point Forces or Distributed Forces by specifying Location, FX, FY, or Magnitude, then set Support Constraints such as Fixed, Pinned, or Roller to define boundary conditions.
3
Click Calculate Results to generate reactions, shear, bending moment, slope, and deflection values for the configured beam.
4
Review the results displayed below, which include plotted deformation and allow switching Display Units between US and SI systems.
5
Use the Clear All or Load Example buttons to reset inputs or populate sample configurations for reference.
