Trebuchet

Designing a Trebuchet – Optimizing Weight and Length

Optimisation of Trebuchet:

1. The length of the payload arm should be 3.75 times longer than the counterweight arm.
2. The length of the sling should be the same length as the payload arm.
3. The initial angle between the counterweight arm and the support should be 45 degrees at launch.
4. The counterweight needs to be 133 times as heavy as your intended projectile.
