History

Which effect results when ancient Chinese crossbow mechanisms experienced increased friction?

A)Deformation from thermal expansion occurs
B)Decreased projectile range occurs
C)Faster string degradation occurs
D)Trigger mechanism lockup occurs

💡 Explanation

Decreased arrow velocity and projectile range happened because overheating leads to viscosity increase in lubricants which created larger drag; therefore, decreased range affected trajectory, rather than thermal mechanisms or direct trigger failures.
