Conversely, a positive acceleration means that the change in the velocity points in the positive direction. Kinematics is the correct use of the parameters position, velocity, and acceleration to describe motion. Learning to use these three terms correctly can be made much easier by learning a few tricks of the trade.
Modern machine building uses gear pairs and multiple keyings of complicated form and structure. This includes two-parametric gear pairs and those with sinusoidal, involute and Novikov-Wildhaber profiles, as well as spline shafts and external splines such as, e.g., those with polygonal surfaces [1, 2, 10, 18].The increasingly complicated form …
