Which 2 factors affect the amount of torque on an object? _______________ and _______________

• Force and distance (lever arm)

• Mass and volume

• Speed and acceleration

• Temperature and pressure

A mechanic is trying to tighten a bolt using a 0.4m long wrench and applies a force of 123N. What is the amount of torque that she applies?

• 49.2 Nm

• 32.5 Nm

• 61.5 Nm

• 82.0 Nm

Where should she hold the handle on this wrench so she can get the MOST torque?

• At the end of the handle, farthest from the bolt.

• Near the middle of the handle.

• Close to the bolt, near the head of the wrench.

• Anywhere on the handle gives the same torque.
