The objective of this project is to build an electrical circuit that is similar to one found in certain doorbells. The project consists of making an electromagnet which causes a switch to open and close causing a buzzing sound like an electric door buzzer. Familiarization with concepts of forces, compression, tension, deflection, and strain.
Materials consist lengths of pine and builders glue.
The project involves one of various cross-section design, analysis, drafting, layout and construction. In some cases mentors may need to provide weights. The objective of this project is for the student teams to assemble a basic catapult from a kit supplied to them and then determine its performance. The teams should vary the adjustable points of the catapult to observe the change in performance. Data taking is encouraged as there will be a competition testing the teams accuracy at hitting targets at various distances.
