1. Project 3: Energy Car
Duration: 6 cycles

2. Project 3: Energy Car Design Brief:
The power of a car is come from the engine. No matter it is petrol engine, diesel engine or electrical engine, is also the process of changing energy. Try to use a steel wire to store the energy for providing power to the car.

3. Project 3: Energy Car Requirement:
The steel wire is the only energy provider, no other power is allowed.
The steel wire must be the part of the car, not to be a shooter.

4. Project 3: Energy Car Requirement:
3. There is no size limit for the car. You may put materials in your design other than provided.
4. Longer distance running is recorded, higher mark will be given.

5. Project 3: Energy Car Material provided: Balsa, 900 x 10 x 10mm
Foam Board (High density rubber foam), 5mm thickness
Steel wire, 17 swg (Ø1.4mm)
Cotton string
Wooden rod, Ø5mm
Hot glue
Cable ties
