Question Paper
1. Write short notes on the following:
Modulus of Elasticity
Yield Strength
Eutectoid Steel
Tempering
Fibre Reinforced Plastic
Galvanizing
Quenching
2. Explain, in detail, the stress-strain curve for a ductile material with proper sketch. Illustrate all the major points on the curve.
3. Define Heat Treatment. List the types of heat treatment processes. Explain, in detail, the heat treatment process of annealing.
Explain the different types of mechanisms of lubrication.
What are the functions of cutting fluids? Why are oil-water emulsions used as cutting fluids?
What is creep strength and rupture strength?
How does strain rate influence yield strength and ultimate tensile strength
A hammer weighing 100 N at the end of a swinging arm of length 400 mm is lifted to a height of 1000 mm from the level of Charpy test specimen. With what speed will the hammer strike the specimen?
6. Explain, in detail, the manufacturing process for reinforced plastic parts, with neat sketches.
