Which one of the following engines will have heavier flywheel than the...
Explanation:
The weight of the flywheel of an engine depends on several factors including the type of engine, the number of cylinders, the power output, and the operating speed. In general, engines with higher power outputs and lower operating speeds tend to have heavier flywheels to maintain smoother operation and reduce vibrations.
In this case, we have four engines with the same power output of 40 horsepower but different operating speeds and types. To determine which engine will have the heaviest flywheel, we need to consider the factors mentioned above.
40 H.P. four-stroke petrol engine running at 1500 rpm:
- Four-stroke petrol engines typically have lighter flywheels compared to two-stroke engines due to their more frequent power strokes.
- Operating at 1500 rpm is a moderate speed, but not particularly low or high.
- Overall, this engine is unlikely to have the heaviest flywheel.
40 H.P. two-stroke petrol engine running at 1500 rpm:
- Two-stroke petrol engines tend to have heavier flywheels than four-stroke engines due to their less frequent power strokes.
- Operating at 1500 rpm is a moderate speed, but not particularly low or high.
- This engine is a possible candidate for having a heavier flywheel, but we need to consider the other engines as well.
40 H.P. two-stroke diesel engine running at 750 rpm:
- Two-stroke diesel engines also tend to have heavier flywheels than four-stroke engines due to their less frequent power strokes.
- Operating at 750 rpm is a relatively low speed, which means the engine may require a heavier flywheel to maintain smooth operation.
- This engine is a possible candidate for having a heavier flywheel, but we still need to consider the last engine.
40 H.P. four-stroke diesel engine running at 750 rpm:
- Four-stroke diesel engines typically have heavier flywheels compared to four-stroke petrol engines due to their higher compression ratios and slower combustion process.
- Operating at 750 rpm is a relatively low speed, which means the engine may require a heavier flywheel to maintain smooth operation.
- Based on these factors, this engine is the most likely candidate for having the heaviest flywheel among the four options.
Therefore, the correct answer is option D, 40 H.P. four-stroke diesel engine running at 750 rpm.
Which one of the following engines will have heavier flywheel than the...
D because first to check four stroke engine then after to check lower speed then heavier flywheel.
