Beam Deflection Calculator

• beam deflection calculator supporting simply supported, cantilever, and fixed-end beams with point loads and uniformly distributed loads
• Automatically calculates deflection, shear force, and bending moment with visual charts

1. Open the tool page — no installation needed
2. Select the beam type and load type, then enter the span length, load, elastic modulus, and moment of inertia
3. Click "Calculate" to view the deflection, shear force, and bending moment results; the chart can be exported as PNG or reset
