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.

Velocity - Distance - Time

• Speed (Velocity) is a change in distance per unit time. SI unit: meters per second (m/s)
• Distance is a length. SI unit: meters (m)
• Time is needed for things to change. SI unit: second (s)

Table of Ions

Note:

• Fe2+ is called Iron(II) this will combine with O2- oxide as FeO Iron(II) Oxide (black iron-oxide)
• Fe3+ is called Iron(III) this will combine with O2- oxide as Fe2O3 Iron(III) Oxide (red rust)
• S2- is called the Sulphide Ion and is different to SO42- the Sulphate Iron
