Answer:
a) Torque
Explanation:
Torque is defined as the first derivative of its angular momentum w.r.t time, basically the twisting force that causes rotation.
Mathematically, it is the cross product of the force applied and the perpendicular distance to an axis of rotation.
T = rFsinӨ = r×F
Examples of torque are the opening of the nut and the tightening of the bolt using a double-arm spanner. The torque applied to the bolt by the spanner is the product of force and moment arm.
