Explain the phenomenon involved in wringing of slip guages
Answers
Explanation:
Slip gauges are high-precision measuring instruments, used for testing, inspection along with comparators. Wringing is nothing, but removing the atmospheric air between two mating surfaces of any two gauge blocks, so that the blocks stick to each other due to vaccum.
hope it's help
Answer:
When two flat, smooth surfaces come in close touch with one another, a phenomenon known as wringing occurs. As a result of the strong adhesion, a group of blocks stacked together almost function as one block. Individual blocks can be manipulated and moved without altering their positions. Furthermore, if the surfaces are smooth and clean, the thin film will adhere to them.
The distance between the blocks will likewise be very thin. This implies that piling, the overall dimension with a combination of several pieces with known dimensions low mistake.
Explanation:
Due to adhesion force.
combination of two factors appears to ensure this high adhesion force. an atmospheric force of 1 bar is acting in the direction shown by the two arrows. This is contributing to the adhesion of the surfaces of the two slip gauges.
Secondly, the surfaces are in such close proximity that there is molecular adhesion of high magnitude that creates a high adhesion force. Since the slip gauge surfaces undergo lapping as a super finishing operation, material removal takes place at the molecular level. Since some molecules are lost during the lapping operation, the material is receptive to molecules of the mating surface.
