The instantaneous center of velocity is the point on a mechanism where the velocity of any point on the mechanism is zero at a given instant of time. In an inverted slider crank, this point is located at the intersection of the connecting rod and the line extended from the slider's path of motion.
The instantaneous center of velocity helps to determine the direction and magnitude of the velocities of different points on the mechanism. This can be useful in analyzing and designing mechanisms for specific purposes.
The instantaneous center of velocity can be calculated by drawing a velocity diagram for the mechanism and locating the intersection point of the velocities of the slider and connecting rod. Alternatively, it can also be calculated using mathematical equations based on the geometry of the mechanism.
The position of the instantaneous center of velocity can be affected by the length of the connecting rod and the angle of rotation of the crank. It can also be influenced by the speed and direction of motion of the slider.
While the instantaneous center of velocity is a point where the velocity of a point on the mechanism is zero, the instantaneous center of rotation is a point where the velocity of any point on the mechanism is purely rotational. In most cases, these two points may not coincide, except in special cases such as pure rolling motion.
