Click to edit Master subtitle style 2) Rotation about a fixed axis v = d r /dt = x r ω ω = ω k a = α x r + ω x (ω x r) k is the axis of rotation. You may have to calculate the axis of rotation if it does not line up with the usual i, j, k axes. r is the position vector drawn from any point on the axis of rotation to point P.

Example Axis of rotation aligned with rod AB. We found in class that axis k is: k′ = 0.8 i - 0.36 j + 0.48 k Then ω = 10/s ( 0.8 i - 0.36 j + 0.48 k) r is measured from anywhere on the axis of rotation. In this problem, it is convenient to measure from either point A or point B. Since we are calculating velocity and acceleration of point E, the vector could be either r E/A or
