Which of the following is a discontinuity that occurs during the casting of molten metal and is caused by splashing, surging, or interrupted pouring?

If a material has identical elastic properties in all directions, it is said to be-

At the point of contraflexure

The property which permits a material to be drawn out longitudinally to a reduce section is called

For the isotropic materials, the stress-strain relationship is known as

Limit of proportionality depends upon

The area under stress strain curve represent

Modulus of resilience is

A shaft of diameter 'd' and length 'l' has been loaded axially, the ratio of change in diameter to the original is called

What is the unit of strain?

When the section is subjected to axial pull or push acting normally across the section the stress so produced is generally known as

The ratio of stress induced due to sudden applied axial load to stress induced due to gradually applied axial load on a bar is

If the poisson's ratio of a material is 0.25, the ratio of modulus of rigidity to the Young's modulus is:
