Matt

I have not gone through the calculations above, but if the Lewis formula give gives tells you your gear tooth is 70% of the strength you need, I am pretty confident that your gear is plenty strong enough for a FIRST applicition.


I have had good success using just a straight beam calculation as an estimate of the strength of the gear teeth. Here is a relatively easy web application from efunda that can do the calculations for you.
