The Car Formerly Known as BOOM

In ENGRI 1170, Cornell University's intro to MechE course, the final car project focused on tasks including a 12m speed test, pulling force test (based on car weight), and a tug-of-war against other designs. The design emphasized the latter two challenges by incorporating wheel axle locking via cutouts in the frame and using a low hook winch. Despite its unconventional strategy, it excelled due to the low coefficient of friction of Sorbothane, enabling more pulling force than any other car. Made from laser-cut acrylic, the car is assembled with structural zip ties. Laser-cut plywood wheels, lined with Sorbothane for traction, rotate on 36 tooth VexPro gears, allowing quick gear swaps between drive shafts and winches during competition.
