Real Life Application: Velocity analysis is prerequisite for acceleration analysis which further leads to force analysis which is the base for design of any machine element.
By velocity analysis we determine the velocity characteristics (linear and angular) of all links of a mechanism at a given configuration, when the input velocity is specified.
Velocity Analysis is the prerequisite for acceleration analysis which further leads to force analysis of various links of a mechanism. To facilitate such study a machine or mechanism is represented by a skeleton or a line diagram.
Velocities and accelerations in machines can be determined either analytically or graphically .With the invention of calculators and computers, it has become convenient to make use of analytical methods .However a graphical analysis is more direct and is accurate to an acceptable degree and thus cannot be neglected .There are two methods of graphical approach Relative Velocity Method Instantaneous Centre Method.
