QUESTION: 2

Notched bar tests are frequently used for testing the

Solution:

Notched bar test- Impact Strength of a Material
Indentation Test- Hardness of a Material
The machinability rating is determined by measuring the weighted averages of the normal cutting speed, surface finish, and tool life for each material.
Salt Spray/Fog Test- Corrosion resistance of the material.

QUESTION: 3

In the creep test, the following type of stress is applied to the specimen

Solution:
QUESTION: 4

A free bar of length / is uniformly heated from 0°C to a temperature t°C, α is the coefficient of linear expansion and E is the modulus of elasticity. The stress in the bar is
Solution:

Since the bar is free to expand, no stresses will be developed in the bar.
