[QUOTE=bassin_bug;390901]I would like to submit these questions, please.

(1) A gear traveling at 2200 rpm is 1.75" in diameter and is driven by a gear 3.5" in diameter. What is the speed of the larger gear?

(2) A gear traveling at a speed of 120 rpm is driven by a gear traveling at 480 rpm. If the smaller gear has 16 teeth, how many will the larger gear have?

(3) A gear 4 cm in diameter has 24 teeth, and it meshes with a gear having 36 teeth. What is the diameter of the other gear?

(4) Are you studying plane geometry?



Okay, you have already answered #5 so I removed it from the list.

Here are the answers to the first three questions.

#1 1100 rpm
#2 64
#3 6 cm
