Question: 1 / 400

What does a plumb bob provide in carpentry?

A horizontal reference line for cutting

A vertical reference line for construction

A plumb bob is a tool used in carpentry to establish a vertical reference line. It consists of a pointed weight attached to a string, which uses the force of gravity to indicate true vertical. When the plumb bob hangs freely, the tip directly points down to the ground, allowing carpenters to ensure that elements such as walls, columns, and door frames are perfectly vertical. This vertical reference is essential in construction to maintain structural integrity and alignment.

While horizontal references and leveling surfaces are important in carpentry, these tasks typically involve tools like levels and chalk lines rather than a plumb bob. Similarly, although a plumb bob can assist indirectly in installing door frames by ensuring vertical alignment, its primary function is specifically to assist in establishing a vertical line, making it the best choice in this context.
