Question Paper
Mention the units for the following mechanical quantities: Force, work, energy, acceleration and power in CGS, FPS and SI systems.
Stress is measured in units Ibf/m^2 in the English system of units. Derive the factor to convert to units and kgf/m^2.
Differentiate between precision and accuracy.
A resistor has a nominal stated value of 10 ± 0·1 Q. A voltage difference occurs across the resistor and the power dissipation is to be calculated in two different ways:
P=EI
In only a voltage measurement will be made, while both current and voltage will be measured in Calculate the uncertainty in the power for each case when the measured value of E and I are:
E 100±1 V (for both cases)
1=10±0·lA
Explain with a neat diagram the essential conditions of interference and clearance fits.
Differentiate between Hole-base system and Shaft-base system.
Classify the gauges based on different criteria.
Differentiate between standard and limit gauges.
5. List the essential parts of a micrometer and explain its working, giving a neat sketch.
6. Give the classification of comparators and differentiate between mechanical and pneumatic comparators.
Discuss the limitations of the use of a sine bar.
Describe the working of an auto-collimator.
8. What are the various types of projectors Mention the advantages of optical projectors.
9. Explain the working principle of co-ordinate measuring machine with a neat sketch.
10. List the common sources of light used for interferometry and explain the essential properties of light wave for interference.
