Absolute Motion Analysis - Crankshaft

Check out https://www.engineer4free.com/dynamics for more free engineering dynamics tutorials. The course covers linear motion, projectile motion, circular motion, kinetics, work & energy, impulse & momentum, and rigid body rotation. Typo: at 3:20 I write d^2x/dx^2 but it should have been d^2x/dt^2. This tutorial goes introduces Absolute Motion Analysis, which is a method that we can use to solve general motion problems. It doesn't make use of any relative motion information, and only takes the absolute position and velocities into consideration. This method will usually involve using the Law of Cosines, or Law of Sines in order to relate a changing angle to a changing length when a triangle is superimposed over the diagram. This method will always involve applying the Derivative Chain Rule, and as you will wee, sometimes multiple times in a row for nested functions.
