Steam to drive an old-fashioned steam locomotive is supplied at a constant gauge pressure of 1.9 × 106 N/m² to a piston with a 0.19 m radius. By calculating PAV , find the work done by the steam when the piston moves 0.81 m in J. Note that this is the net work output, since gau pressure is used. W = Now find the amount of work done by calculating the force exerted times the distance traveled in J.
