(2) Reciprocating Motion to Rotary Motion. The force of the piston acting in a
downward notion is of little immediate value if it is to turn the wheels of a
vehicle. In order to use this straight line or reciprocating motion, it must be
transformed into rotary motion. This is made possible through the use of a
crankshaft. The crankshaft is connected to the driving wheels of a vehicle through
the drive train on one end. On the other end of the shaft is a crank with a
crankpin offset from the shaft's center. Figure 3 on the following page
