Poisson's ratio is defined as the ratio of Lateral strain and longitudinal strain.
The strain energy stored in a body due to external loading within the elastic limit is known as resilience.
1. The maximum strain energy which can be stored in a body upto the elastic limit is called proof resilience.
2. The proof resilience per unit volume of a material is known as modulus of resilience.
A scalar quantity is defined as the physical quantity that has only magnitude, for example, mass and electric charge.
On the other hand, a vector quantity is defined as the physical quantity that has both magnitude as well as direction like force, weight, acceleration and velocity.
Pig iron is the intermediate product extracted from iron ore in a blast furnace.
Pig iron is used as raw material in steel making.
Pig iron gets its name from the old fashioned method of casting the iron into moulds arranged in sand beds so that they could be fed from a common runner.
