Resilient materials Have high ultimate tensile strength Have

Resilient materials: Have high ultimate tensile strength Have high yield strengths and low moduls of elasicity Are used in spring application Both a mid b Both b and c...

Solution

Q4

The correct answer is option C

Option A is false because the resilient materials allow high strains but low stress because they have a low modulus of elasticity, so may not have a high ultimate tensile strength.

Obtion B is false because they do not have a high yield stress due to previous explanation.

D and E options include A or B so they are false.
