Question

Simple machines make work easier. Most simple machines reduce the amount of effort force needed to move an object. In this wheel and axle system, the wheel and axle is used to pull a bucket up. A person turns the handle (P), using effort force. What if the bucket is really heavy and the wheel cannot be turned? How can the effort force be reduced so the bucket can be lifted?

Answer 1

Answer:

Simple machines can actually make more work due to friction. Simple machines make work easier to do by decreasing the force required by increasing the distance over which the work is done.
