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.

D. The blessed hearer and doer applies the word so that it changes his conduct and his character in the sight of God. In contrast to the worthless religion of the man in 1:26, in 1:27 James gives two practical examples of a person who applies Godâs word. He is not being comprehensive, but is zeroing in on two areas of pastoral concern.
