- Torque CalculatorMoment of a force, τ = r × F; SI and customary torque units per NIST SP 811Torque is the turning effect of a force about an axis, and it depends on three things: how big the force is, how far from the…
- Moment of Inertia CalculatorStandard rigid-body mass moments of inertia and the parallel-axis (Huygens–Steiner) theoremChoose a body shape, enter its mass and its characteristic dimension, and this calculator returns the mass moment of inertia…
- Centripetal Force & Acceleration CalculatorUniform circular motion; relative centrifugal force per the standard RCF relationAnything moving in a circle is accelerating towards the centre, and something has to supply the force that produces that…
Which one do you need?
- Torque Calculator
- Calculate torque from force, lever arm length and the angle between them, or back-solve the force or radius, with newton-meters and pound-feet shown.
- Moment of Inertia Calculator
- Find the mass moment of inertia of a rod, disk, hoop, cylinder, sphere or plate, shift the axis with the parallel-axis theorem, and get stored energy.
- Centripetal Force & Acceleration Calculator
- Calculate centripetal force and acceleration from mass, speed and radius, with the equivalent g-force and the friction- or bank-limited cornering speed.
