Do not rely on the book’s illustration alone. Draw the velocity or acceleration vectors separately to visualize the directions of (angular velocity) and (angular acceleration).
If you know the directions of the velocities of two points on a body, the IC is located at the intersection of the lines perpendicular to those velocity vectors. Hibbeler Dynamics Chapter 16 Solutions
is constant, use kinematic equations analogous to linear motion: Point Motion on a Rotating Body Velocity ( A point at distance from the axis has a linear velocity magnitude: v equals omega r Acceleration ( Composed of two perpendicular components: Tangential ( Changes the speed; Normal/Centripetal ( Changes the direction; Magnitude: General Plane Motion This is a combination of translation and rotation. Relative Velocity Equation: The velocity of point can be found relative to a known point Do not rely on the book’s illustration alone
