Use this engineering calculation for a transparent preliminary estimate or independent arithmetic check when geometry, materials, loads, operating conditions, and units are defined consistently.

Load Newtons Per Meter (N/m)

Required number input.

Span Meters (m)

Required number input.

Each end reaction of a simply supported beam carrying a uniformly distributed full-span load. The tool evaluates the supplied inputs together and returns the named outputs below; it does not infer omitted operating conditions or change the units shown.^[1]

Reaction Newtons (N)

The resulting reaction newtons returned as a number.

• Simple beam equations assume stated supports, loads, linear elasticity, small deflection, and an appropriate section property. Shear deformation, local buckling, lateral-torsional buckling, cracking, creep, connections, dynamics, and code combinations may govern.
• Use finite inputs in the displayed units and preserve more precision than the final presentation requires. Independently verify safety-critical, financial, compliance, or production decisions.

Check assumptions against drawings, measurements, current material data, and the applicable design code. Apply required load combinations and safety factors, then obtain qualified review and testing for consequential designs.

• Beam Max Moment Uniform

  Maximum sagging moment wL²/8 in a simply supported beam with a full-span uniform load.

• Beam Deflection Cantilever Point

  Free-end deflection of an ideal prismatic cantilever under a point force at the free end, neglecting shear deformation.

• Cam Lift Simple Harmonic

  Simple-harmonic cam follower displacement over a specified rise angle, with zero at start and full lift at end.
