Claw hammers and pulleys are examples of simple machines that do what to the direction of force applied by the user?

• Correct Answer: reverse it
• nothing
• neutralize it
• maintain it

Explanation: Some machines change the direction of the force applied by the user. They may or may not also change the strength of the force or the distance over which it is applied. Two examples of machines that work in this way are claw hammers and the rope systems (pulleys) that raise or lower flags on flagpoles. Figure below explains how these machines work. In each case, the direction of the force applied by the user is reversed by the machine. How does this make it easier to do the job?.
