Steam to drive an old-fashioned steam locomotive is supplied at a constant gauge pressure of 1.95 × 106 N/m2 to a piston with a 0.23 m radius.
50% Part (a) By calculating PΔV , find the work done by the steam when the piston moves 0.84 m in J. Note that this is the net work output, since gauge pressure is used.
W = 2.72 * 105W = 272000 ✔ Correct!
50% Part (b) Now find the amount of work done by calculating the force exerted times the distance traveled in J.
W =
