What is a free-body diagram?

Itâ€™s a sketch of a body in motion that shows bending forces of the body

Itâ€™s a sketch of an undisturbed body that shows external forces of the body

Itâ€™s a sketch of a moving body that shows internal forces of the body and reaction forces

Itâ€™s a sketch of an isolated body that shows external forces of the body and reaction forces

Correct Answer : Option (D) : Itâ€™s a sketch of an isolated body that shows external forces of the body and reaction forces

Explanation : A free-body diagram is a drawing of an isolated body that depicts external forces operating on it as well as reaction forces imposed by removing parts.

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.
