Q1:

A material being tested for endurance strength is subjected to the __________ load.

A impact

B completely reversed

C dynamic

D static & dynamic

ANS:B - completely reversed

A material being tested for endurance strength is subjected to the completely reversed load. Endurance strength testing involves applying cyclic loading to the material, where the load alternates between tension and compression, often at high frequencies. This simulates the repetitive loading conditions that materials experience in real-world applications, such as in machinery components subjected to alternating stresses during operation.
