Learning Goal: The velocity of any point B in a rigid body can be described by VB = VA+WX IBA where w is the angular velocity, IBA is the relative position vector from point A to point B, and vA is the velocity of point A. Choosing point A to have zero velocity, VA = 0, simplifies the equation to VB=WXTBA The point chosen such that the velocity is zero is called the ..
