Along with this question, I have another.

If a train weighing 130 pounds is headed up a 14 degree incline pulling two 75 pound cars, what is the mininum coefficient of friction (mu) that the train can have between its wheels and the tracks?

My answer: .53 assuming all wheel drive -- it is worse if only one set of wheels is driving.

Teams that plan on just driving up that sea-saw without much thought are in for a surprise!
