TSny said:Are you using the center of rotation of CBD to find vD?
Your red arrow representing the direction of vD is incorrect.
The Instant Center of Velocity (ICV) is a point in a moving body where all particles of that body have zero velocity at a given instant in time. It is also known as the instantaneous center of rotation or instantaneous center of zero velocity.
The ICV is calculated using the relative velocities of two points on a rigid body. The ICV is located at the intersection of the perpendicular bisectors of the lines joining the two points and their corresponding velocities.
The ICV is significant in kinematics as it helps determine the direction and magnitude of the angular velocity of a rigid body. It is also used in the analysis of planar motion and the design of mechanisms.
Yes, the ICV can change as the body moves and its particles change their velocity. The ICV will always be located at the intersection of the perpendicular bisectors of the lines joining two points with their corresponding velocities at a given instant in time.
The ICV is used in various fields such as robotics, biomechanics, and vehicle dynamics. It is used to analyze and design complex systems that involve rotational motion, such as robotic arms, human body movements, and vehicle suspensions.
