anyone else done mousetrap cars for physics?
heres my design so far(minus all teh materials) in inventor
the square up front is the mousetrap which will have a lever arm attached to pull on the “cvt” on the intermediate axle this will give me variable speeds not just one. and then another pulley that goes back to the main axle. the wheels will be made out of desktop and laptop harddrive disks cnc’d out. i have the intermediate axle because my teacher has restrictive size requirements. the frame will be made out of foam board then covered in fiberglass and if i feel like it carbon fiber for looks. the 1/8th" shafts will be riding on tiny little open bearings for minimum rolling resistance. the grading as i remember it is the total distance travalled/time for the first 5m.
