For the lifting system below :
1. prove that : D2/D1=N2/N1 where that D1,D2 are the diameter of the driver and driven gear respectively. and N1 and N2 are the RPM for the driver and the driven gear respectively.
2. For the lifting system shown above, Gear B is used to lift the Box C, if driving gear A is rotating at 30 RPM, find the linear speed of the box C.

so π*D1*N1/60=π*D2*N2/60
π and 60 it will cancel each other in both sides
So it will be D1*N1=D2*N2
Now collect similar letters in one side
D1/D2=N2/N1
