Catapult Research Paper

942 Words4 Pages

This science fair project is a mechanical catapult that will be electrically modified to pull back on its own. The goal of this project is to see how far an eraser cap will launch with two different forces that pull the catapult arm forward very fast. From this, we will see if either a bungee cord, or fifty to one-hundred rubber bands has more elasticity. One real-world situation we would want more elasticity for is holding things together, or hooking things together. In this project, recording of the control and data trials will be included into a bar graph, as an average. The control trial is the launch distance of the bungee cord. The data trial is the launch distance of the rubber bands. The trials will be tested ten times each so a better …show more content…

    1245 Words  | 5 Pages

    The onager used a hook with a pouch that would carry a boulder compared to the catapult which used the spoon mechanism. The reason the Romans preferred the hook and pouch was because it was more accurate than the spoon (Dugdale-Pointon). The onager had an elevated crossbeam that would operate as a stopping point. A swing arm was placed in a bundle of rope that would be winched down until it reached a slip hook. The hook would then be released, and the arm would fling forward until stopped by the crossbeam.

    Bolts and stones for these early ballistae were assembled on the battlefield. These smaller ballistae required little specialized knowledge to build, and consequences for mistakes wouldn’t be as severe as most parts were wooden and able to be easily remade. The later, and much larger, ballista were made of large amounts of metal and delicately cut wood. Mathematicians and professional artisans were needed to design and build these weapons. Their massive projectiles (some exceeding 150lbs) were pre-rounded by craftsmen and thus had to be transported.

    In this egg drop project, a container was built to house one egg and was then dropped at various heights. The purpose of this lab was to find how impact time affected the force with which an object, the egg container, hits another surface as the momentum moves to zero. Our hypothesis states that if the impact time is stretched longer then the force exerted on the egg would decrease, making the egg less likely to break. The independent variables for the egg drop project was the height at each drop; the dependent variables were impact time and survival of the egg. The controls were mass, design of the container, and the egg.
