Friction-reducing technologies used in the Variable Compression Turbo Engine are Diamond-like coating on valve lifters, micro finishing on crankshaft and camshaft and mirror bore coating on cylinder wall.
<u>Explanation:</u>
Variable compression is a technology to adjust the compression of an internal combustion engine while the engine is in operation. At this time friction may occur that need to be reduced. To reduce this friction some technologies are used like
- Diamond-like coating on valve lifters
- Micro finishing on crankshaft and camshaft
- Mirror bore coating on cylinder wall
A hydrogen free diamond like carbon coating is applied to an engine valve lifter to reduce mechanical loss. Micro finishing on crankshaft and camshaft achieves improvement in geometric parameters such as roundness. Mirror bore coating on cylinder wall raises energy efficiency by reducing the friction inside the engine.
It's a longitudinal wave surely because information passes parallel to the direction of travel or something like that?
Answer:
C
Explanation:
It would have to be a bus with a ramp.
Think about it, an inclined slope is kinda like a right triangle, and its a ramp, ramps go down :)
Answer:
Explanation:
Given
Total run=198 m
maximum speed=317 m/min=5.28 m/s
acceleration
(a)Distance traveled while accelerating
s=12.57 m
time taken
v=u+at
t=4.75 s
(b)Time taken to cover 198 m
if car takes 12.57 m & 4.75 s to reach max speed so it also takes 12.57 m and 4.75 s to stop from max speed
Distance traveled with max speed=198-25.14=172.86 m
time taken
total time=4.75+32.73+4.75=42.25 s
