Match the items in column 1 and column 2 and choose the correct combination.
Column 1 | Column 2
---|---
A - Resilience | 1 – Ability of the material to return to the original shape when load is removed
B – Fatigue | 2 – Capacity of a material to absorb energy elastically
C – Stiffness | 3 – Ability of material to absorb a certain amount of energy without failure
D - Elasticity | 4 – Resistance of the material to elastic deformation
| 5 – Failure of material at loads less than that at normal conditions
Correct Answer: B — A - 2, B - 5, C - 4, D - 1
Explanation:
Concept: The correct match is, Resilience - Capacity of a material to absorb energy elastically Fatigue - Failure of material at loads less than that at normal conditions Stiffness - Resistance of the material to elastic deformation Elasticity - Ability of the material to return to the original shape when the load is removed Resilience It is the total strain energy stored in a given volume of material within the elastic limit. On removal of a load, this energy is released. In other words, it is the area under the load-deflection curve within the elastic limit.
