Torque is a crucial concept in physics and engineering, representing the rotational force around an axis. It’s particularly important in machinery and mechanical systems where rotational motion is involved.
Formula
The torque output (τ\tauτ) is calculated using the formula:
τ=F×d\tau = F \times dτ=F×d
where:
- τ\tauτ is the torque (newton-meters)
- FFF is the force applied (newtons)
- ddd is the distance from the pivot (meters)
How to Use
To use the Torque Output Calculator:
