1. Gear machines: Gear machines use gears to transmit power from one component to another. The velocity ratio is determined by the ratio of the number of teeth on the driving gear to the number of teeth on the driven gear.
2. Pulley machines: Pulley machines use rotating wheels with a grooved rim called pulleys to transmit power. The velocity ratio is determined by the ratio of the diameter of the driving pulley to the diameter of the driven pulley.
3. Lever machines: Lever machines use a lever, a rigid bar that pivots around a fixed point called a fulcrum, to transmit power. The velocity ratio is determined by the ratio of the distance from the fulcrum to the point where the input force is applied to the distance from the fulcrum to the point where the output force is applied.
4. Inclined plane machines: Inclined plane machines use a sloping surface to reduce the force needed to lift an object. The velocity ratio is determined by the ratio of the length of the sloping surface to the vertical height over which the object is lifted.
5. Wheel and axle machines: Wheel and axle machines use a larger wheel (the wheel) and a smaller wheel (the axle) connected together. The velocity ratio is determined by the ratio of the radius of the wheel to the radius of the axle.
