Basic Engineering Materials Quiz! - Quiz

What do you know about basic engineering? Basic engineering is an honorable trade. There are certain variables necessary for the work of engineering. Engineering can be separated into two groups. This grouping includes metals and non-metals. Different types of metals are non-ferrous, and others are ferrous. Engineering materials can be classified as metals and alloys, ceramic materials, and organic materials. This informative quiz will teach you about basic engineering.
