Engineer on team #49, Delphi Knights, from Buena Vista High School and Delphi Automotive. In Reply to: Re: also the boy scout motto, kinda... Posted by Justin Stiltner on 1/23/2001 8:14 PM EST: Your engineer is correct, technicaly. The reason cars get more traction with wider tires is because the tire material is so compliant. If you were to ignore the effect of the tires sidewall and ignore the deflection of the tire under torque then the car would get the same amount of traction with skinny tires or fat tires. It doesn't because the tire patch size increases as the tire deflects under torque. I assume that your robot tires will not be deflecting under torque. However, the carpet does deflect some wich causes the robot wheels to behave somewhat different than the classical physics model. I guess my long winded suggestion is to make a couple model wheels and put the same weight on both then pull them across a carpet with a string and a hard scale so you can measure the traction force. Hope this helps. Matt B. T49 |
