Question 7 of 14

8. 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 8 of 14

9. There are some materials that regain their original shapes after being stretched even though they do not obey hookes Law. True or False?

Question 9 of 14

Question 11 of 14

12. What is the name given to materials which do not recover but are deformed permanently under stress?

Question 12 of 14

13. 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?
