According to Newton's first law of motion,

to every action, there is always an equal and opposite reaction

every body continues in its state of rest or of uniform motion, in a straight line, unless it is acted upon by some external force

the rate of change of momentum is directly proportional to the impressed force, and takes place in the same direction, in which the force acts

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.

The term 'force' may be defined as an agent which produces or tends to produce, destroys or tends to destroy motion.
