The hypothesis of our experiment, is to test whether hard materials, would be better suited in the construction and design of a crumple zone, rather than soft materials, as they would provide more protection to the safety and reduction of injuries to passengers in a motor-vehicle.
From the above graph it depicts the average outcomes for each test. According to the control, the graph illustrates that the car experienced a large amount of force in a short period of time. The force was calculated at 17.13 N over an impact preiod of 0.04 seconds, this is considered a highly dangerous amount of force if scaled to a real life situation. This result is unsatisfactory in accordance to the hypothesis as the ideal outcome of the experiment was to create a small force over a large impact time. The control was then used to compare the other following tests. These tests contained two major variables. The soft experiment consisted of materials which varied from the 'hard', these components were two types of low density foam. The graph shows that the car ecountered a miminal amount of force as compared to the 'control', at approximately 7.79 N, over a substantial amount of impact time as opposed to the 'control' and the 'hard' outcome. The time measured 0.09 seconds, which is a difference of 0.05 seconds, in contrast to the 'control'. The 'hard' crumple zone on the other hand, was pinnacle point of our whole experiment. As we hypothesised that the 'hard' materials would be better suited in the design and construction of a crumple zone. This is the reason behind the comparison of the two styles of crumple zones. Lastly the 'hard' crumple zone, tested a significantly small force reading, compared to the 'control', but opposed to the 'soft', it was reasonably high. The force amount was recorded as 9.52 N over an impact time of 0.05 seconds. There are no trends or patterns in these results. They are quite varient to each other.
