A mechanism is defined as a closed kinematic chain in which any one link is fixed.
MECHANISM
• A mechanism is defined as
a closed kinematic chain in which any one link is fixed.
• The mechanism should have
a constrained motion. If all links of a kinematic chain are free, the motion
will be unconstrained. When one link is fixed, it becomes mechanism.
• If different links of a
kinematic chain are fixed, the result is a different mechanism.
• The primary function of a
mechanism is transmit and modify motion.
• A machine is a mechanism
or a collection of mechanisms which transmits both motion and forces.
• The mechanism is a device
to transmit and modify motion. If the device also transmits forces, in addition
to motion, then the mechanism is called as machine.
• It may be noted that all
machines are mechanisms, but all mechanisms are not machines.
• The difference between
mechanism and machine is presented in Table 1.3.
