Try This Reply #15 – October 15, 2007, 04:18:21 PM I don't understand the problems with question 7. That’s one I found easy NOT being able to figure out the "reverse" part. I just skipped "Reverse", and was a no brainer from there, simple process of elimination.. Direct is obviously CReduction is obviously AOverdrive is obviously B Reverse can ONLY be D... I didn’t understand WHY that one was reverse but it just had to be. 19 was one that gave me trouble Quote Selected

I didn’t understand WHY that one was reverse but it just had to be.On diagrams A,B, and C; the driven gear rotates in the opposite direction of the drive gear giving a "forward" momentum. With the extra cog between the 2 in Diagram D, the driven and drive gears rotate in the same "reverse" direction. Quote Selected
