In the previous lecture, we discussed static and dynamic balancing of rotating parts• Main difference between static and dynamic
balancing??Specifically, we looked at a few examples of shafts with disksWe were asked to balance the shaft by adding masses to one or more of the disksLet’s look at similar, but different examples…

Let’s consider the unbalanced link shown below.We would like to balance the ink with a single mass, mb.
In order to do this, we need to essentially make the center of mass of m1, m2, and mb be located at x=0, y=0.
