Which of the following instructions might you suggest that would help her loosen the bolt?
Select TWO answers.
Move her hand closer to the bolt so that the force is closer to the center of rotation which makes it more effective.
Move her hand further from the bolt to increase the lever arm.
Increase the angle of the force to perpendicular to the wrench to maximize the torque.
Change the angle so that the force is angled toward the bolt rather than away from it.
