1.8 kg of nitrogen fills a piston chamber with a volume of 0.038 m3 at 560 kpa gauge. the piston is then moved so that the volume doubles. the chamber is allowed to sit until it again reaches room temperature of 20°c. what is the final pressure in the chamber?

The force on a cutting tool are 2600n vertically downward and 2100 horizontal. determine the resultant force acting on the tool and the angle at which it acts.

An engine runs on the ideal diesel cycle. the cycle has a compression ratio of 20 and a cutoff ratio of 2. the highest temperature in the cycle is 1200 k. if the heat into the system is 300 kj/kg of working fluid and using variable specific heats determine the work produced per mass of working fluid
