Answer:
Both Technician A and B are correct
Explanation:
Due to a contamination of the clutch disc friction surface, the clutch chatters
The contamination that causes clutch chattering includes
1) Worn or broken motor mounts
2) Bell housing bolts becoming loose
3) Clutch link damage
4) Warped flywheel, due to overheating, the flywheel can become warped such that the non uniform surface interfaces the clutch resulting in clutch chattering
5) Engine or transmission oil contaminating the disc.
Answer:
a) the log mean temperature difference (Approx. 64.5 deg C)
b) the rate of heat addition into the oil.
The above have been solved for in the below workings
Explanation:
Answer:

Explanation:
The phenomenon can be modelled after the Bernoulli's Principle, in which the sum of heads related to pressure and kinetic energy on ground level is equal to the head related to gravity.

The velocity of water delivered by the fire hose is:


The maximum height is cleared in the Bernoulli's equation:



Answer:
time = 5.22 hr
Explanation:
Given data:
Energy of battery = 9400 J
Power consumed by three led bulb is 0.5 watt
we know Power is give as

plugging all value and solve for time


time = 18,800 sec
in hour
1 hour = 3600 sec
therefore in 18,800 sec
