What Is Torque (Moment)?
Torque is the effect that rotates an object around an axis. It equals the product of the applied force and the perpendicular distance of the force from the axis.
How is it calculated?
How Is It Calculated?
τ = F × d × sinθ
- Enter the force, lever arm length and angle.
- When the force is perpendicular (90°), torque = F × d.
Unit: newton-metre (N·m).
Frequently Asked Questions
How does the lever arm length affect torque?
As the lever arm gets longer, a greater torque is obtained with the same force; that is why long-handled wrenches turn more easily.
