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…

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

The belt suddenly starts in an upward direction so that slipping instantly occurs between the belt and the boxes. The kinetic friction coefficients between the belt and the boxes are μk,A = 0.3 and μk,B = 0.32. Determine the initial acceleration of each box. Will the blocks stay together, or separate? 80 lb 100 lb A B 15° Hint: to see if the boxes stay together or separate, first assume they separate, and see if their resulting motion (acceleration) validates that assumption. If the their motion is not consistent with the assumption of separation, then they must stay together.arrow_forward
