3. Tilting Pistons
The tilting piston is a double acting cylinder that has a 5-inch bore and an 15-inch stroke. When air is applied
to the bottom port of the cylinder, the piston begins to extend and air is exhausted through the top port. Then,
if air is applied to the top port, the bottom port will exhaust the air which will cause the piston to retract.
