1. A rotary motion , producing a continuous power source suitable for driving machinery. 2. There are'rack and pinion'gears to translate rotary motion into linear motion. 3. In 1781 James Watt patented a steam engine that produced continuous rotary motion . 4. The rotary motion and the timing of the power pulses run with uncanny smoothness. 5. Rotary motion of the motor is converted to linear displacement.6. The limbs could not move alternately as they lacked the necessary rotary motion range. 7. In water-raising devices rotary motion is typically more efficient than machines based on oscillating motion. 8. This rotary motion in my hips and shoulders is much like loading a giant spring. 9. It can also be used as a flexible coupling to transfer rotary motion between shafts. 10. ;Bone Drills : Driven in their rotary motion by means of a thong in various configurations.
