Electric Car | |
| Making an electric car is a mechanical engineering challenge often used as a competition for students from 5th grade to 8th grade.           |
|An electric car is driven by a DC electric motor, powered by one or two batteries.                                                            |
|Transmission of force from the motor to the car axle is accomplished using two pulleys and one rubber band acting as a belt. A simple switch   |
|made of a paper clip is used to connect or disconnect the circuit. Wheels are made of larger pulleys with rubber rings as tires. The car       |
|chassis is mad of a plastic board, reinforced by wood blocks and eye screws that will also support the axles of the wheels.                    |

|Some students may prefer to buy all the parts separately and cut all the woods themselves and design their own car; however, most students and|
|teachers prefer to get all the parts in a kit and make changes as they need.                                                                   |
|With this project students can explore:                                                                                                       |
