Question 1 of 14

2. The resistance a material offers to forces which tend to change its shape or size or both hence not flexible to bending is called?

Question 2 of 14

3. The ability of a material to undergo significant permanent change of size and shape (plastic deformation) without breaking/rupture is called?

Question 3 of 14

4. Hooke's Law states that for a helical spring or other elastic material, the extension of the mateiral is directly proportional to the stretching force provided the elastic limit is not exceeded. True or False?
