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

Shear Newtons (N)

Required number input.

First Moment Meters3 (m³)

Required number input.

Second Moment Meters4 (m⁴)

Required number input.

Section Width Meters (m)

Required number input.

Elastic beam shear stress τ=VQ/(Ib) at a section with supplied first and second area moments and local width. 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]

Shear Stress Pascals (Pa)

The resulting shear stress pascals returned as a number.

• Stress, strain, section, and torsion equations assume stated geometry, loads, supports, material behavior, and small deformation. Stress concentrations, instability, fatigue, fracture, plasticity, residual stress, and code factors 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.

• Bending Stress

  Extreme-fiber bending stress magnitude in an elastic beam section from bending moment, neutral-axis distance and second moment.

• Beam Stress Combined Axial Bending

  Combined elastic normal stress N/A+My/I at a chosen signed fiber coordinate; excludes buckling and local effects.

• Bolt Shear Capacity

  Nominal single-shear force from bolt shear area times a user-supplied allowable shear stress; not a code-rated connection capacity.
