History

Which problem increased when medieval siege engineers increased trebuchet arm length?

A)Torsional stress fractures
B)Kinetic energy inefficiencies
C)Projectile trajectory deviation
D)Counterweight lifting failures

💡 Explanation

Torsional stress fractures increased due to increased leverage. Because the trebuchet arm experiences greater torque, the wood fibers could shear along the axis of twist, therefore weakening the structure rather than converting maximal potential to kinetic energy.
