A couple of days ago, one of our former teachers, Mrs. Smith, was teaching us about forces and pulleys. We attached a rope to a plastic pole and we put our strength to the test! We had somebody pulling the rope and two (or more) people pulling the poles. The person pulling the rope had an easier job. He had mechanical advantage.
Mrs. Smith and Mrs. Dressel tried it. Cody pulled the rope and made them move!
