Design assignment pair work

last time when i post up the whole questions for I n C group project part 2, the whole class just type in the whole question in google search and most of them was so excited when saw the exactly same question in searching engine. Haha, of course finally they are all disappointed when they discover that it's in my blog and of course no answer in it..Thus, this time i won't post up the question here, but roughly its about gear train, torque, moment etc which I almost forgot already. Whatever, have to settle it also.
