Question

define torque qualitatively and quantitatively

Answer 1

When you use a wrench to tighten or loosen a nut on a bolt, you are applying torque. It is measured in units of force times distance, roughly how hard you pulled on the wrench times how long the wrench handle was.

A force of F newtons pulling on a handle of L meters in length would supply a torque of F L newton-meters.

More technically, torque is the vector cross product of force times perpendicular distance from the object, F x r = F r sin @
