Difference between Mechanism & machine

Mechanism
Primary function is used to transmit or
modify the motion.
It is not used to transmit the force.
A mechanism is a single system to
transfer the motion
eg.i) In watch, energy stored on winding
the spring is used to move hands.
ii) An indicator is used to draw P-V
diagram of engine

Machine
Primary function is to obtain the mechanical
advantage
It is used transmit the force
A machine has one or more mechanism to
perform the desired function.
eg. i) Shaper receives mechanical power
which is used to suitably convert to do work
of cutting the metal.
ii) A hoist is machine to lift the loads.
