HOW TO WORK OUT SOLAR PLATES REQUIREMENTS IN URDU
Can you make a car with cardboard, binder clips and paper clips (optional) can only be used for the axles, rubber bands, and clear tape only. The axles can be wood (dowels) and the car cannot be bigger than .400m x .400m x .400m, cardboard must be corrugated. The car has to go 40 ft in a glossy type floor.
Here are my car’s dimensions
1. Each back wheel is made from 6 discs taped together
2. Small cardboard discs used as spacers to keep wheels away from the chassis.
3. Chassis is 400mm long, 100mm wide, sides are 50mm high
4. Axles are pencils because I didn’t have any suitable dowel
I made those wheels extra wide because I wanted them to be relatively heavy to grip the ground. Wrapping rubber bands round them would also improve the grip.
This car is heavily inspired by these two previous projects which would probably both manage the same task.
