Main question -> How does the size of the crumple zone affect the impact force, which on a vehicle is exerted? Theoretical Exploration During a collision, objects exchange momentum and energy, causing them to move. Collisions can be divided into two groups, elastic (resilient) and inelastic (unresilient) collisions. Example of a (completely) inelastic collision is a traffic accident. During the collision, a first distortion occurs, where the colliding objects meet each other. To prevent this, all cars now have one crease zone. The crumple zone is a part of a load-bearing bodywork that absorbs the force of the impact and reduces it as much as possible. The crumple zone includes, for example, the trunk or the front around the engine compartment, …show more content…

Step-by-step plan: Make sure you have all the supplies you need Make the setup above Roll up the aluminum foil and place it over the punch pin by sliding it onto the cart. Make sure the crumple zone protrudes sufficiently. 3x aluminum roll of 5 cm. 3x crumple zone of 10 cm. 3x crumple zone of 15 cm. 3x crumple zone of 20 cm. Place the cart at a certain height on the shelf, and measure the distance with a measuring tape. Place the cart with the aluminum attached to it on the line. And then lets go, have the coaching lab measure the data. The speed, collision time and the force during the collision. Do this 3 times with all lengths. Check carefully whether the results are saved on the laptop. hypothesis. Main question: How does the size of the crumple zone affect the impact force? on a vehicle is being operated? Hypothesis: Larger crumple zone creates smaller impact force. We think that a larger crumple zone would provide less impact force on the center of the car/trolley. This would be because the surface area is larger, so the force is spread over more area. Results 5.0 - 0.01 cm. 2) …show more content…

Answer ->> As the “crumple zone” increases, the impact force becomes smaller and smaller. Explanation Answer ->> As shown by the results of our experiment, the average impact force decreases as the length of the crumple zone increases. This is because a larger crumple zone can absorb more energy during a crash. This reduces the force exerted on the central part of the vehicle. The average Ns for length, clearly shows that the impact force decreases with an increase in the crumple zone. As you can see in the results, is the least punching powergem in length 20 centimeters. With a longer crumple zone, the impact force hitting the center will be much smaller than with a smaller crumple zone. This is because the surface area is larger, so the force is spread over more area. If the research had been done with aluminum foil you would also be able to see how far the indentation/creasing is due to the deadfold of the foil. Accuracy Consideration The potential errors that could happen (or have happened) during the test or the processing of the
