HW #4 Problem 11.3a
HW #4 Problem 11.12
Lecture 19 • 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 disks • We were asked to balance the shaft by adding masses to one or more of the disks • Let’s look at similar, but different examples…
Lecture 19 • 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.
Lecture 19 Example
Lecture 19 • Let’s consider the two-plane dynamic balancing problem
