Re: Gravity Vehicle C

Instability definitely. There's a reason why cars nowadays have 4 wheels instead of 3. I may be wrong, but I think that there is another possible disadvantage to 3 wheels. windu said that a large wheelbase is less prone to drifting (wheel slippage and stuff), so my guess is that a 3 wheeled design ...

Re: Gravity Vehicle C

I was planning on doing the exact same thing, though I'll be ordering carbon fiber rods online instead of 3d printing them (can't say I wouldn't be jealous if you actually have access to a 3d printer that can use CF :P ). Obviously the size of the rod/stick used will make a difference in the streng...

Re: Gravity Vehicle C

An "interference fit" means that a piece is very slightly bigger than the hole that it fits into. So once you've forced it together, friction keeps it from moving. In this context, it means threading a short plastic tube around the threaded rod, and then forcing the plastic tube into the bearing. T...

Re: Gravity Vehicle C

I don’t get what you mean by an interference ring for the axle and the bearing. Is it threaded and very thin so it can be glued to the bearing or is it attached with nuts. If you could explain that would be really great.(sorry I’m having trouble understanding ) An "interference fit" means that a pi...

Re: Gravity Vehicle C

One thing that I've never figured out in my time in vehicle events such as mousetrap vehicle and scrambler was (a) How do high skill competitors get threaded rods into ball bearings such that there is no play between the rod and the bearings, (b) it seems that an adjustable start height for the veh...

Re: Mousetrap Vehicle C

Would taking off the locking pin on one of the mousetraps be considered illegal? And what type of string is recommended? Sorry for the barrage of questions.
