Question Paper
1. What are fits and tolerances? How are they designated
2. A hole is dimensioned as 25+0·033 +0·0 and the shaft is dimensioned as 25-0·040 -0·061 Determine the hole tolerance, the shaft tolerance and allowance of the fit. What type of fit shall be established?
3. What do you mean by in measurement Explain the different types of errors.
4. Explain the formation of interference fringes when light falls on an optical flat resting on a lapped surface. What is the effect of using a monochromatic, instead of white light?
Describe in brief the principle of a micrometer screw measuring device.
State a particular precaution which must be taken when using an external micrometer to measure a diameter.
Why is it important to use the ratchet, when taking measurements with a micrometer?
What is meant by "accuracy" of a measuring instrument?
How do you distinguish between "repeatability" and "stability" of an instrument?
What is the difference between "magnification" and "amplification"
What is the meaning of calibration of measuring equipment What is its principle?
Why sometimes a measurement system in use, does not conform to its calibration
What is meant by 50 H 5 What is the fundamental deviation of this hole?
You have received an e-mail message in which the fit for an assembly is specified as H52 H7/ 852 06. What do you understand by the above designated fit
List out a few advantages of Mechanical Comparators.
Draw a neat sketch of anyone mechanical comparator.
10.(a) Make a list of gauges that are used in production. Describe two of them which are applied on internal surface.
Name the gauges to be used for the following:
Pulley
Wire
Thread
Shaft
Sketch two of these gauges and mention the material of which they are made.
11. Sketch and describe anyone of the following:
Inside spring caliper
Inside firm joint caliper
Transfer caliper
12.(a) What is a sine bar How is it used to measure an angle between two surfaces Can you measure all angles with this arrangement?
What is the purpose of a Spirit level? How does it differ from clinometer?
