What are subassemblies in engineering?
Subassemblies in engineering refer to a group of components that are assembled together to form a part of a larger system or product. These subassemblies can be used to simplify the design and manufacturing process by breaking down complex systems into smaller, more manageable parts. By creating subassemblies, engineers can focus on designing and optimizing individual components, which can then be easily integrated into the larger system.
