5.1 Key findings
The friction of the wheels affects the distance travelled by the car.
The mass of the car affects the speed and distance travelled.
Friction between the wheels and the ground can be increased by adding a layer of rubber on the wheels.
5.2 Comparisons with other designs based on research
Our car should have a longer lever to move further.
5.3 Evaluation of engineering goals
Our mousetrap car can travel at least 5 meters and more.
our car is less then 10 cm wide and tall, but it is slightly more than 30 cm long
5.4 Areas for improvement
The lever arm could be longer, delivering a longer power stroke and hence the car would move further. We could also use ball bearings between the axle and the car body to minimise friction and allow it to move further. We also could have positioned the mouse trap further in front of the car. Finally, we also can have made the car smaller, resulting in less mass, so that it requires less force to start the car.
5.5 Practical Applications
This experiment allows us to experience what car mechanics do and allows us to appreciate vehicles better. Using this experiment, we will know how to build better axles and wheels for future projects.
5.6 Areas for further study
We could build more models of MTVs with different specifications to find out what affects the distance in which a mouse trap vehicle (MTV) can travel. For example, build cars which are very wide, some very thin, some powered with the front wheels and so on.
