So, back to the original question about what MOD means. Well MOD is the ratio of the pitch circle diameter (PCD) to the number of teeth. DP for imperial gears is the number of teeth per one inch of pitch circle diameter. So whilst that may well answer the question, it doesn't really help appreciate the size of a gear.

You spelled it right in the question: does. The word does (performs action) is a verb, and the plural of the noun doe (female deer). Many people mix up two similar words: doseâ¦ and does. Dose is a noun and is the amount of medication prescribed. Does is a verb, a form of to do.
