Beam calculators

Deflection, bending moment and stresses of straight beams.

• Simply supported beam with a central point load

  Deflection, bending moment, stresses and diagrams. Deflection and bending moment are both largest at mid-span, under the load.

• Simply supported beam with a uniform load

  Deflection, bending moment, stresses and diagrams. Deflection and bending moment are largest at mid-span; the shear force is largest at the supports.

• Cantilever beam with a point load at the free end

  Deflection, bending moment, stresses and diagrams. The bending moment and stress are largest at the fixed end; the deflection is largest at the free end.

• Cantilever beam with a uniform load

  Deflection, bending moment, stresses and diagrams. Bending moment, stress and shear are largest at the fixed end; the deflection is largest at the free end.
