    Would any of you smart fellas out there help me?

    A wheel and axle is a machine made so the wheel (large diameter) and axle will rotate at the same speed. A resistance of 85.0 N attached to the wheel, is displaced by an effort of 275 N. The machine has an efficiency of 78.5%. If the axle has a diameter of 8.00 x 10^-2 m and makes 3 revolutions, what is the displacement of the resistance?

    Any help is appreciated. Thanks, guys.
