A crank is an arm at right angles to a shaft (an Axle or spindle by which motion is imparted to or received from the shaft it is also used to change circular into Reciprocating A flywheel is a mechanical device with significant Moment of inertia used as a storage device for Rotational energy.
James Watt, who was a contemporary of James Pickard, circumvented the latter's patent by inventing an alternative mechanical device, the so called sun and planet gear. James Watt ( 19 January 1736 &ndash 25 August 1819 Boulton proved to be an excellent businessman and both men eventually made fortunes The sun and planet gear (also called the planet and sun gear) was a method of converting reciprocal motion to Rotary motion and utilised a reciprocating Steam
