i wanted to know if the flow in the exhaust pipe of an ic engine cross the sonic speed? i have been seeing a lot of papers presented about the supersonic internal flows on the net and hence i wanted to know some of the practical situations where such flows can be seen?

but what is the use of a floating or separating piston in a monotube shock absorber when u can use a plastic bag of nitrogen between the inner and outer tubes??

nitrogen gas is said to prevent cavitation in shock absorbers and thus provide a comfortable ride.. i want to know what actually happens in a shock absorber when nitogen gas is used. how does it prevent cavitation?

disc brakes i want to know for disc brakes. 100 lbs is a large force! can a person apply that much of force while he is seated on the pedal? i want to know how a person who is about 130 to 150 lbs apply that amount force??

what is the approx brake pedal force that a person applies while braking on the brake pedal?

what is the approximate weight of brake system used in cars? will disc brakes increase the weight?

yeah right! but what is the maximum limit upto which u can raise water just using capillarity and without the aid of external energy?? isn't it possible by making a tube of very small diameter??

capillarity has the power to raise water.. then can it be used to pump water to greater heights?
