Essay On Trebuchet

The trebuchet is made of five basic parts. The base, counterweight, throwing arm, sling, and pivot. The base gives the trebuchet a secure base to help with over rotation and other engineering problems that may occur. The counterweight falls and the force of gravity thrusts the projectile forwards. The throwing arm is used to connect the counterweight and sling, and is part of the thrust downwards.The sling holds the projectile and the pivot is there to prevent over-rotation. Trebuchets can be made from many things, and some parts can be made of different materials. Wood is most commonly used for small-scale projects, but metal and plastic are other options. The material chosen must be easily accessible, and available at close stores. Therefore making wood or plastic the best option. Also, the material used must be strong but also able to be broken apart and put back together. When the counter-weight falls, its
When the trebuchet is fired, the weight box falls, and the force of gravity causes rotational acceleration of the attached throwing arm around the axle. The sling is attached to the end of the throwing portion of the throwing arm (opposite the counter weight portion). The sling contains the projectile and thrusts the projectile forwards. The sling also changes the trajectory, so that, at the time of release from the sling, the projectile is traveling in the desired speed and angle to give it the range to reach the target. A teacher could use this to show both potential and kinetic energy. In a history classroom, a treuchet could be used to highlight the medieval times. Trebuchets will most easily fit into a science or math classroom, but I also think that History is an option. As for the lesson plan, in History, the students would learn the history of the trebuchet, and then would be able to see one in real life. In math and science, a trebuchet can be used as an example of both kinetic and potential
