What is the formula for torque on a lever arm?
What is the formula for torque on a lever arm?
- $\tau = \frac{F}{r}\sin\theta$
- $\tau = Fr\sin\theta$ (correct)
- $\tau = F\sin\theta$
- $\tau = Fr\cos\theta$
What components are needed to calculate torque?
What components are needed to calculate torque?
- Lever arm, point of rotation, and angle of rotation
- Lever arm, force, and point of rotation (correct)
- Force, point of rotation, and angle of rotation
- Lever arm, force, and angle of rotation
What is the role of the lever arm in calculating torque?
What is the role of the lever arm in calculating torque?
- It determines the angle of the force
- It has no impact on the torque calculation
- It provides the distance from the force to the point of rotation (correct)
- It directly influences the magnitude of the force
