Physics

Calculate torsional stiffness from GJ/L or torque and twist, with solid, hollow, and direct-J options plus unit handling.

Calculate true strain from engineering strain or lengths, compare the difference, and optionally convert engineering stress to true stress.

Calculate von Mises stress from plane stress, principal stresses, or 3D tensor inputs, with yield check and factor of safety.

Calculate Young’s modulus, stress, or strain with unit-aware inputs and a built-in note for linear elastic range checks.

Calculate Vickers hardness (HV) from force and indentation diagonals, with SI conversion, mismatch check, and report-ready notation.

Convert volume to mass using density with clear unit handling for metric and US units, plus base-unit checks and display options.

Calculate angular acceleration, time, torque, or angular velocity with unit-safe inputs and clear sign meaning.

Find angular displacement from angles, arc length, angular velocity, or angular acceleration with clear degree and radian handling.

Convert angular frequency, frequency, period, and rpm, or read omega directly from a sinusoid coefficient.

Calculate angular momentum for rigid bodies, point masses, and conservation with unit conversions and a shape-based inertia helper.
