Mechanics is the branch of Physics dealing with the study of motion. It is the science which deals with the physical state of rest or motion of bodies under the action of the forces. The major division of the mechanics discipline separates classical mechanics from quantum mechanics.
Exp- To measure the force required under static conditions to displace the mass the same distance against the pull of the spring.
Dual scale allows to take readings clock or anticlockwise.
Free movement of Pulley reduces friction.
Precise measurement of angle with the built-in-scale. By changing mass or angle a little equilibrium position changes immediately.
