Question
Mechanics sometimes use a piece of pipe to lengthen the handle of a wrench when trying to remove a very tight bolt.How does this increase the torque? Group of answer choicesIt increases the lever arm.It increases the force you can apply.It changes the angle you can apply the force relative to the lever arm.
Solution
The use of a piece of pipe to lengthen the handle of a wrench increases the torque by increasing the lever arm. Torque is the rotational equivalent of linear force, defined as force times the distance from the pivot point (in this case, the bolt). By using a longer handle, the distance from the pivot point is increased, which in turn increases the torque. This allows the mechanic to apply the same amount of force but achieve a greater result. This does not necessarily increase the force you can apply, but it does make the force you apply more effective at generating torque. The angle at which the force is applied relative to the lever arm remains the same, so it does not contribute to the increase in torque.
