Mousetrap cars can have 3 or 4 wheels, which one is better?Some have large wheels in the back and small wheels in the front, while some have large wheels in the front and small wheels in the back, does this change anything?I‘m making a mousetrap car with distance in mind, not speed.
one size fits all usually fit nothing.id get the one made for your car.
Yes. Cars can be struck by lightning. No. The tires do not protect them. Think about this for a moment, a giant electric spark just jumped through a VERY LARGE distant. What is going to keep it from also jumping the twelve inches or so of air gap from the car to the ground? Besides which the carbon black used in the tires to make them black (you did know that both natural and synthetic rubber are black because of the additives, right?) is very conductive at the voltages involved so they don't do that good a job of insulating the car in the first place. That said the metal of the car might protect you from the lightning by shunting the electricity around you. I say might because the metal is discontinuous and is not a perfect Faraday cage.
For simplicity use the four wheels. The set of drive wheels can be on the front or back. The diameter of those drive wheels will determine the distance traveled for each revolution of the those wheels - the larger the diameter, the longer the distance.
