Re: Mousetrap Vehicle B
Is there a reverse direction need or pushing the cup is needed in 2020 MouseTrapVehicle B challenge? Is there an official rules defined somewhere?
Thanks,

Re: Mousetrap Vehicle B
Rule 3.e states, "In the ready to run configuration, all wheels/treads (in their entirety) must fit in a 40.0 cm x 40 cm space of any height and any orientation." Does that mean you could set your vehicle upright like its doing a wheelie, and make your vehicle infinitely long? Or do all 4 wheels have to be touching the ground?

Re: Mousetrap Vehicle B
It must be in the "ready to run configuration" meaning however your vehicle will start is how it has to fit in the 40x40 square. In other words yes, all 4 wheels must touch the ground when ready to run and thus when measured.Epicbanna4 wrote: ↑Mon Nov 04, 2019 3:06 pm Rule 3.e states, "In the ready to run configuration, all wheels/treads (in their entirety) must fit in a 40.0 cm x 40 cm space of any height and any orientation."

Re: Mousetrap Vehicle B
Clarification question. Construction Parameter 3a. state that "No part of the jaw/hammer may extend more than 1.0 cm beyond the base." Then goes on to state, "Items may be added to the mousetrap through methods including, but not limited to: soldering, taping........"
Most designs that I have seen include an added length of material to the "jaw/hammer" that extends the distance traveled in order to apply the force to the axle more effectively than with the regular jaw/hammer. Does this rule mean that we cannot extend more than 1 cm beyond the base, or does it mean that the original jaw/hammer cannot extend more than 1cm beyond the base? Thanks in advance.

Re: Mousetrap Vehicle B
Would the best approach be to make the lever arm attached to the mousetrap longer or shorter? In other words, distance or speed?

Re: Mousetrap Vehicle B
Alright. So the rules state that the jaw/hammer must not extend 1 cm longer than the wooden base of the mousetrap. The metal Jaw/hammer cannot be modified (like bending, cutting, melting, etc.) to achieve better mechanical advantage. However, yes, people have added a drive arm to the jaw/hammer. Hopefully that helps. Good luck!mdejong wrote: ↑Wed Nov 06, 2019 8:47 am Clarification question.

Re: Mousetrap Vehicle B
Why is this 1cm jaw/hammer even a rule? Are there mousetraps where the metal snapper (aka jaw) does not snap down completely on the wood base? I wouldnt think for an optimal mouse stike, there would need to be a solid surface under the jaw, not one that sticks out past the base.Epicbanna4 wrote: ↑Thu Nov 14, 2019 8:27 pmAlright.

Also, anybody know why we have to add a 20 cm wood dowel? I don't think a photogate can be used since the time score is the entire run. It still seems like an overkill to serve only as the start point.

Re: Mousetrap Vehicle B
Well that makes more sense. Thanks for sharing. It still wouldn't work because of the dimension the base is required to be. But I guess they are just covering all angles with the extra rule.bearasauras wrote: ↑Sat Nov 16, 2019 1:42 pmThis has been seen at tournaments before.builder83 wrote: ↑Sat Nov 16, 2019 6:55 am
