How do you build an adjustable catapult?
To build an adjustable catapult can be very simple. If you are using materials that spring forwards, as most catapults do, then all you would have to do is vary the distance that you pull it back. If you are using a trebuchet design, a lever arm pulled down by weights and flinging an object, you can vary the amount of weight. Hope it helps.
