Everyone in a class has to run the same size tire. You can very the rubber compounds either hard or soft. The sled does start out stationary and the object is to pull it 300ft. The momentum build up is used to overcome some of the friction as the weight of the sled is transferred forward onto...
Sorry, I would like to know the maximum wheel speed limit to move the sled.
If the wheel speed is too great the rubber melts and looses traction. If the wheel speed is too slow there isn't enough momentum to keep the sled moving as the resistance increases.
I need a little help understanding something. I was wondering if it is possible to understand the physics behind sled pulling? From what I can tell is there are two major factors in pulling 1) being the coefficient of friction needed to move the sled (14,000lbs of weight over 2, 5'x1' pieces of...
