Velocity of a Point on a Link by Instant Center Method
{"Image DocumentName": "Velocity of a Point on a Link by Instant Center Method", "Image ImageDescription": "Consider two points A and B on a rigid link. Let vA and vB be the velocities of points A and B at a given instant. If vA is known in magnitude and direction and vB in direction only, then the magnitude of vB may be determined by the instantaneous centre method. Draw AI and BI perpendiculars to the directions vA and vB respectively. Let these lines intersect at I, which is known as instantaneous centre or virtual centre of the link. The complete rigid link rotates about the centre I at the given instant. The relations shown may be used to determine the magnitude of the velocity of point B.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
