What is the difference between circular runout and total runout?
Answer Posted / viswa
Runout is a composite control which results due to form,
orientation and location errors in a part. Runout is a
surface characteristic. It is always checked by rotating
the part about a datum axis and observing the full
indicator movement (FIM) of a dial indicator whcih is in
contact the the surface of the part. The tolerance zone of
runout error is a liner distance between two circles
concentric with the datum axis.
Concentricity, on the other hand, is only a locational
error of the axis of a feature with reference to the datum
axis. The tolerance zone is always cylindrical in case of
concentricity which is centered around the datum axis.
Concentricity in a plane is checked by finding the position
of the median points of the profile along different
orientations in that plane by using two dial indicators in
contact with the surface of the part and observing their
differential readings. All these readings should be less
than the specified concentricity tolerance.

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
