You apply force to a wrench to tighten a bolt. The wrench breaks in half. Select the best answer for what happens next. Assume the force applied remains constant.

The torque is now half of what it was, because torque and distance are inversely proportional

The torque is now half of what it was, because torque and distance are directly proportional

The torque is now double of what it was, because torque and distance are inversely proportional

The torque is now double of what it was, because torque and distance are directly proportional
