When i did it the string was only really a problem when it was really stretchy such as twinedoes the type of string used affect the distance the car can travel?
If yes then I would llike to try sewing thread(any stiff threads) fishing line and any other stretchy type of string.
Read the Mousetrap Vehicle Wiki there is a whole section on ways to make it workanyone know how to make the vehicle go backwards? please??? thanks!
Check out 3.a. in the rules. It tells you there that "unmodified" means that all the original parts have to be there, but that you can add things to it or drill holes.On the wiki, it says to add a bar to the trap. But, isn't that modifying it and thus breaking the rules?
It should say wind x times to travel y meters. The relation between x and y will depend on the ratio of the axle to wheel diameters. I think I'll work over that page later tonight.For the third example on the wiki, it says to wind the string x times around the axle to travel x meters. Does this assume that the circumference of the circles is 1 m, or is the ratio of winds to wheel turns not 1 to 1 because of some other factor?
There a a couple of waysAlso, building on the last question, how can one guarantee that the string won't fall off or have a slip thus messing up the distance? Do you just, say, do something like tape the end of the string (obviously not the winding) to the axle or something?
