The other five machines all help humans increase and/or redirect the force applied to an object. Alternatively, a long handle can be attached to the axle to achieve a similar effect. If a wheel is attached to an axle, and a force is used to turn the wheel, the rotational force, or torque, on the axle is much greater than the force applied to the rim of the wheel. In addition to reducing friction, a wheel and axle can also serve as a force multiplier. – Perpetual motion machines: Working against physical laws
