Note: the 2018 Engineering Challenge is over, but you can still do this project on your own! The objective of the 2018 Engineering Challengewas to use limited materials to build one device (the launcher) that launches an aluminum foil ball and another device (the receiver) that catches the ball. The farther your ball flies before being successfully...
Make sure you read and understand all the contest rules before you start.If you are unsure how to start designing, try these tips:Once you have decided on a design, build it. If you are working with a team, you may want to assign different jobs to each person in the group to make sure everyone gets a chance to participate. Fo...You might need to modify your design, even as you build it! For example, you might discover that two parts do not fit together like you thought they would. This is OK and a normal part of the engin...Crumple up a sheet of aluminum foil (12"x12" or 30x30 cm) into a wad with a diameter of less than 2 inches. This will be your "ball."Experiment with your launcher. Try using it to launch the aluminum foil ball.Experiment with your receiver. Try using your launcher to launch the ball into it and/or just throwing the ball at the receiver. Remember that you cannot touch the receiver during a test.If you are working with teammates, discuss your observations as a group. You might want to modify your launcher and/or receiver design before you start official testing. Remember that this is OK! R...When you are ready to do an "official" test and calculate your score, follow these steps: 1. Place your launcher and receiver on a long, flat surface, like the floor or a countertop. 2. Use a tape measure to measure the horizontal distance in centimeters between the front of the launcher's base and the closest point on the receiver, as shown in Fig...
Calculate your score using this equation: 1. The distance in centimeters is the distance between the launcher and the receiver, as shown in Figure 2 2. The materials cost is the sum of the point costs for all the materials used in your final design, as defined in Table 1
