History

In early cast iron crossbow trigger mechanisms, which consequence occurred when exceeding the metal's yield strength?

A)Permanent deformation jams the sear
B)Increased accuracy compensates material flaw
C)Greater flexibility absorbs impact force
D)Decreased friction enables smoother release

💡 Explanation

Permanent deformation occurs because exceeding yield strength causes irreversible crystal lattice slip within the metal, resulting in plastic deformation and jamming the sear through a mechanism of plastic yielding. Therefore, the sear loses tolerance, rather than improving accuracy, due to the material change.
