Final answer:
The claim that an adjustable wrench should only be used when other wrenches do not fit is false. Option B is correct.
Step-by-step explanation:
The statement that an adjustable (present) wrench should be used only when other types of wrenches will NOT fit is False. An adjustable wrench is a versatile tool that can be used on different sizes of nuts and bolts. However, using the correct sized wrench provides a better fit and reduces the risk of slipping and damaging the fastener or hurting oneself.
Tools like socket wrenches or a power drill are highly efficient in situations that involve multiple nuts and bolts of the same size, or when dealing with a situation that requires more torque or speed than a manual wrench can provide.
Mechanics often use a length of pipe over the handle of a wrench to remove a tight bolt. This practice, known as a cheater bar, increases the leverage and thus the torque applied to the bolt. It is, however, potentially hazardous as it can exceed the design specifications of the wrench and bolt, leading to breakage and possible injury.
While socket wrenches or a power drill are efficient for repetitive or high-torque tasks, and adding a pipe to a wrench handle increases leverage, caution is needed to avoid breaking tools or bolts.
