Question

10. Torque vector is directed along (a) the tangent to the circular path (b) the inward radius (c) the outward radius (d) the axis of rotation​

Answer 1

Torque is directed along the tangent to the circular path.

• Torque is the force that causes an object to rotate about an axis.
• We know that force causes linear acceleration while torque causes angular acceleration.
• Torque T = r F sin α, where T is the torques, r is the radius, F is the force and α is the angle between F and lever arm, Therefore, torque acts along the tangent of the circular path.
