What is one characteristic of the face of a pole?

The face of a pole is indeed referred to as the concave side. This terminology is used in various utility and construction contexts to describe the shape and orientation of the pole itself. The face typically refers to the side that is oriented toward the primary load or direction of stress, which is critical in determining how the pole interacts with environmental forces such as wind or the weight it supports.

Understanding this aspect helps utility professionals in identifying how poles should be installed and maintained, ensuring that they can endure the conditions they face while serving their intended purpose.
