The door is 1.2 m high and I m wide, and the top edge of the door is 8 m below the free surface of the water. Determine the hydrostatic force on the er of the door, and discuss if 10 the masse door if it is located at the center o if the driver can open the door, if Answer the following statements by True or False: 1. Superchargers are used to increase the power of an IC engine by raising the intake pressure and thus allowing more fuel to be burned per cycle. 2. Scavenging is the process by which the oil rings scrape the lubricating oil from the cylinder wall and allow the oil to return to the oil pan. 3. The power output of a two-stroke engine equals that of a four-stroke engine for the same displacement. 4. After coolers are used after the compressor to drop the air temperature and thus increase its density. 5. The rotary…

The rotary engine has the advantages of better sealing of high pressure gases and less wear on seals.
