What type of work is restricted to licensed mechanical engineers in Michigan?

Licensed mechanical engineers in Michigan have specific responsibilities and restrictions that are crucial to public safety. One of their primary roles is to perform critical design and engineering oversight that directly affects public safety. This includes evaluating systems, designing mechanical solutions, and ensuring compliance with safety standards, building codes, and regulations. These functions often involve the direct application of engineering principles and the assessment of risks associated with mechanical systems.

While other areas like consultation, research and development, and project management can involve engineering knowledge, they do not carry the same level of direct responsibility for public safety that is imposed on licensed professionals in design and oversight roles. Thus, the critical aspect that identifies the correct answer is the focus on responsibilities that directly impact public safety, which is legally reserved for licensed engineers in Michigan.
