Excerpt from Appletons' Cyclopedia of Applied Mechanics, Vol. 2 of 2: A Dictionary of Mechanical Engineering and the Mechanical ArtsThat is to say, the angular velocities are to each other inversely as the perpendiculars from the cen tres of motion upon the common normal or, inversely as the segments into which the common nor mal cuts the line of centres. And if it be required that the velocity ratio shall remain constant, it follows that the common normal must always cut the line of centres in the same point.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
