Let us see what is Theory of Machines
This subject DEALS with the study of 1.Relative Motions of Machine parts in (action) Motion 2.Forces acting on various parts of the machines at rest and in Motion
This study elaborates in four branches 1. Kinematics 2. Dynamics 3. Kinetics 4. Statics
KINEMATICS - Explains and establishes the relative motions between various part of Machines
DYNAMICS - Explains and establishes the Forces and their effects on various parts of the machine in motion.
KINETICS - Explains and establishes the Inertia of force due to mass and motion of the machine parts.
STATICS - Explains and establishes the Forces and their effect when machine parts at rest assuming the mass of the parts aa negligible(0).

International Standard Units shortly mentioned as S I units
Basic Units / Fundamental Units are 1 . Length - Meter 2. Mass - Kilometer 3. Time - Seconds
Derived Units ( means units ( arrived ) derived from Fundamental Units may also called as Secondary Units.
Mass density - kg/m3 Force - N Pressure - Pa / N/m2 Work / Energy - J / Nm Power - J/s / W Absolute viscosity - kg/m-s
Kinematic Viscosity - m2/S Velocity - m/S Acceleration - m/S2 Angular acceleration - radian/S2 Frequency ( in Hertz ) - Hz
