Trebuchet Catapult

A counterweight trebuchet swings its arm and hurls a projectile in an arc across the field, its launch speed set by the falling counterweight's torque and its trajectory bent by crosswind.

• Frame: A-frame wood truss + steel axle
• Physics: driven arm rotation → tangential release velocity
• Cycle: cocked → swing → flight → landed → reset
• Gravity: shapes both fall speed and swing feel
