It's been close to 50 years since college so I'm not sure where to go with this problem.
I have a grinder that has a 16000 rpm motor, one pulley .875 diameter and one pulley 2.230 diameter. There are 7 driven speeds from 3200 to 46200, how do I calculate the minimum number of pulleys required to get the seven different speeds? At the low end of the range the speeds are rounded to 10 to 25 rpm and at the top end 50 to 100 rpm.
