Principles of Engineering
This is a page from my own engineering notebook that I created when I went to the training for POE.
One important thing it illustrates is a progression of design changes to part of a larger machine. The changes involve how to physically attach certain components so that the entire subassembly can pivot as a unit.
Also of note are the following:
a) clear statement of a problem with the design and a possible solution
b) clear labels of major components
c) dates of different entries on this page
d) gear ratio and MA calculations, with separate diagram identifying each gear
