Torque
Compute moment, rotational force, and torque vectors. Free online calculator with formulas and step-by-step solutions.
Key formula
tau = rFsin(theta)
About this tool
Torque describes the turning effect of a force. The educational value here is seeing that rotational influence depends not only on force size, but also on lever arm and angle.
How to use this calculator
- Choose the variable you want to solve for and confirm which values are already known.
- Enter inputs in consistent units before calculating so the formula is applied correctly.
- Check whether the result is physically reasonable by comparing it with the size of the inputs.
- Use the step-by-step breakdown to see how the equation was rearranged and evaluated.
