Re: pic: KING TeC 2169 Lift Gear
Events and pictures like this one create "teachable" moments, and that is a good thing. One of the best things about the FRC, I believe.
Three ways to take advantage if you have not already done so:
(1) get the lead mechanical engineering mentor on your team to explain how stresses on gear teeth are calculated, or
(2) seek help with (1) from one of the fine mechanical engineers who designed this gear [looks like VexPro to me], or
(3) seek advice from one of the many experts who follow CD.
After working through the stress analysis, try to understand the loading conditions that caused the 14T gear in your elevator drive to become over-stressed. Then (depending on the cause) you might look for design improvements to keep it from happening again.

I believe in intuition and inspiration. Imagination is more important than knowledge. For knowledge is limited, whereas imagination embraces the entire world, stimulating progress, giving birth to evolution. It is, strictly speaking, a real factor in scientific research.
