2STROKE ENGINE
1.In case of tow stroke engine their are four event 1 Suction
2.Compression 3.power 4exhaust ,this four Event are completed
in four moment of piston and one power stroke is obtain one revolution of crank shaft,hence it is called 2Stroke engine.
2 .The rate of fuel consumption is high.
3 .The life of engine is Less as compared to 4stroke because,of more wear and tear in two stroke engine.
4. Running cost is high ( i.e more consume fuel )
5. pick-up is high but efficiency is less.
6. carbon diposiation in engine is high due to fast moment of crank shaft.(i.e 1 moment)
7.Operating cost is less.
8.In case of two stroke engine noise is high .
7.Compression Ratio is high.

4 STROKE ENGINE
1 In case of 4Stroke engine their are 4 event 1.suction2.compression3.power4.exhaust this four event are completed in four moment of piston and power stroke is obtain 2 revolution of crank shaft hence it is called 4Stroke engine.
2.The rate of fuel consumption is Low
3.The life of4Stroke engine is high because of Less wear and tear.
4.Running cost is Low .(less consume fuel as compared to 2Stroke engine)
5.pick-up is Less but efficiency is high.
6.Carbon diposiation is Less because of slow moment of crank shaft (i.e 2 moment)
7.operating cost is Less
8.In case of 4Stroke engine noise are Less.
9.Compression ratio is Less.

Greetings This question is about hydraulics and I request an expert to answer it. A simple hydraulic machine is made up of two heads, a larger one with a larger force inside a wider pipe and a smaller one with a smaller force inside a smaller pipe in width as in the second picture on this link: http://science.howstuffworks.com/hydraulic1.htm The question is this: what happens if the smaller head and the smaller force doesn’t exist but the smaller pipe is high enough to take all the liquid? For example the larger head is 1.00 sqr metre and can go down 1.00m under a weight of 100.00kg. The cross sectional area of the smaller pipe is 0.001 sqr metre. Now when the larger head goes down 1.00m, how high the liquid from the wider pipe can go into the smaller pipe of the cross sectional area of 0.001 sqr metre? Regards
