Answer

Brief Explanations:

A breaker bar is a long - handled tool that provides greater leverage. When an impact wrench (which uses rotational force with impacts) fails to loosen a fastener quickly (within 3 - 5 seconds), the breaker bar's increased leverage can overcome the resistance of the fastener. An air ratchet is a power tool for rapid, low - torque rotation (not for high - resistance fasteners). A torque wrench is for tightening to a specific torque value (not for loosening stubborn fasteners). A regular ratchet (without the leverage of a breaker bar) is less effective for very tight fasteners.

A. Breaker bar
