Wheels and Crazy Spinning Things!
For the illustration of the following model, go to http://www.corniceventures.com/images/wheels.JPG
If the 2 wheels ("B1" and "B2") are the same diameter (40 inches) and are rolling forward at 4 miles per hour...Would belts "D1" and "D2" rotate hubs "C1" and "C2" respectively at the same rate (rpm's)?
Here are all the parameters:
"B1" and "B2" Diameter >> 40 inches
"A" Diameter >> 12 inches
"C1" and "C2" Diameter >> 1 inch
Here is what my calculations told me:
"B2" Circumference >> ~125.66 inches
"A" Circumference >> ~37.70 inches
"C1" and "C2" Circumference >> ~3.14 inches
"B2" RPMs at 4 MPH >> ~33.61 rpm
"A" RPMs at 4 MPH >> ~112.05 rpm
"C1" and "C2" RPMs at 4 MPH >> ~1344.54 rpm
To me it seems that belt "D2" would rotate hub "C2" more quickly than belt "D1" would rotate hub "C1" given the same forward speed, but maybe I should trust my calculations! Any help would be appreciated, thanks in advance!
