Question
### Multiple Choice Question: **Concept: Torque** Torque is the rotational counterpart of force, but it is not force. It has the tendency to rotate objects. The torque is more effective when: 1. The force is larger 2. The force is far from the axis of rotation 3. The angle between the radius (r) and the force is zero **Choices:** a) Only (1) is correct b) Only (2) is correct c) All (1), (2), and (3) are correct d) Both (1) and (2) are correct **Explanation:** Torque (\(\tau\)) is calculated as the product of the force (\(F\)) and the lever arm distance (\(r\)) from the axis of rotation, with consideration of the angle (\(\theta\)) between them: \[ \tau = r \cdot F \cdot \sin(\theta) \] - A larger force increases torque. - Greater distance from the axis of rotation makes the torque more effective. - If the angle is zero, \(\sin(0) = 0\), meaning no torque is generated when the force is aligned with the lever arm.
