Coefficient of restitution for perfect elastic bodies is 1.

Which of the following type of screws is used in the machines?

Round-threaded

Helical-threaded

Square-threaded

Rectangle-threaded

Correct Answer : Square-threaded

Explanation : In the machines, square threaded screws are employed. Because screws are commonly employed as fasteners. The fundamental benefit of screws is that the friction aids in the structure’s retention. Screws also aid in the fast and efficient joining of the structure.
