Final answer:
Peel and stick non-skid is classified as non-critical in the engineering field.
Step-by-step explanation:
Peel and stick non-skid is classified as non-critical in the engineering field.
Non-skid refers to a surface treatment or coating that provides grip and prevents sliding or slipping. While non-skid is important in various applications such as flooring, stairs, and decks, it is not considered critical in terms of safety or structural integrity.
This classification is based on the fact that non-skid is not a primary or essential component of a structure or system, but rather an added feature for convenience and improved safety.
