Catapult diy1/30/2024 You can also calculate the amount of energy transferred to the tennis ball using the distance it traveled and its weight. Input energy can be calculated using the formula: E=mgh where ‘m’ is the mass of the weight, ‘g’ is the gravitational acceleration on Earth (9.8) and ‘h’ is the height. When you know the energy stored in the weight and how far the projectile can be thrown, the energy going into the system and the energy released can be measured. The ‘potential’ energy is transferred to the arm and sling of the trebuchet and is released as kinetic energy in the tennis ball.” In 15 Dangerously Mad Projects for the Evil Genius, author Simon Monk says, “The trebuchet takes its energy from the weight that falls as the arm swings. A catapult has a cup at the end rather than a sling. A rope is wrapped around a rotating drum and when the spring mechanism is released, so is the arm and the projectile. The catapult uses a leaf spring mechanism to release the long arm. The sling increases the length of the arm and the performance. The counter-weight uses the pull of gravity to provide the force necessary for the arm to swing upwards. A trebuchet uses a sling and has a counter-weight which, as it is dropped, forces the long arm up to pull the sling and the projectile along a slide at the base. There is a difference between a trebuchet and a catapult. Depending on the size of the trebuchet you build, you will probably be throwing smaller objects, like tennis balls. Usually it was large rocks, but often dead and rotting livestock were thrown. Trebuchets have been around since the middle ages and were often used to throw objects at the enemy’s fortress. As Halloween comes around, wouldn’t you like to spend your weekend building your very own pumpkin-launching trebuchet? A trebuchet is a medieval engine of war with a sling for hurling missiles.
