I'm doing this project for school and I need some serous help. The project is biulding a model car body,running it with one 1.5 volt battery. It has to pull 6 ounces of load and, pull the load up a 25* angle ramp, and have 2 working headlights. The battery has to last for up to 6 heats. I have no idea where to start. Any help would be appreciated.

Thanks

by one 1.5volt battery I assume you mean one standard AA battery one couldnt use say a much larger amp powersupply if it only put out 1.5volts right... also would the car have to be entirely self contained? Do they supply you with the materials or not? Little more specifics on the rules could be nice...

set the gearbox up like a winch so the car can't roll backwards. i'd use leds for head lights. you want a small drive gear and a large one on the axel to get your car has more of that torque stuff. You�d want your tires to have a nice amount of surface area.

That shouldnt be too hard. Just make a few simple gear box's connect them to 4 motors (one for each wheel) and connect them in parralel to the battery.
