Answer Posted / nithin mathew
Boring bars are used for enlarging an existing drilled hole. Even though we have fine finish boring bars, its surface finish will be poor compared to other finishing processes.A comparatively large amount of material is removed in this process.
Reamers are used for finishing an existing hole. we can get up to N6 finish by reaming and an Ra up to 0.8.
Lapping is a super finishing process where abressive powder is rubbed against the surface in a lubricating environment. We can get below N5 finish through this process.

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
