When gasoline is burned in the cylinder of an engine, it creates a high pressure that pushes on the piston. If the pressure is 150 poundforce per square inch, and it moves the 3inch diameter piston a distance of 6 centimeters in 0.1 seconds, how much horsepower does this action produce?

John

Power = Work/time = Force*distance/time
The force, of course, is pressure*area
Now just put things into the proper units and it all falls out.posted by Steve
