What does the lever arm represent in the equation L = r sin θ?
What does the lever arm represent in the equation L = r sin θ?
- The angle between the force and the radius of rotation
- Distance from the axis of rotation to where the force is exerted (correct)
- The net torque produced
- Magnitude of the force applied
How is torque calculated?
How is torque calculated?
- Torque = Force ÷ Distance
- Torque = Force ÷ Lever Arm
- Torque = Force × Lever Arm (correct)
- Torque = Force × Distance
