What are the main duties of a mechanical engineer?

I'm considering mechanical engineering as a major in college. Could anyone break down what mechanical engineers actually do on a day-to-day basis? I'm curious about the kinds of projects they typically work on and what skills are most essential.

Mechanical engineering is a broad field with numerous possible roles and responsibilities, but there are some common duties and skills which most mechanical engineers share.

On a day-to-day basis, a mechanical engineer could be involved in designing and analyzing systems, conducting research to solve complex problems, or developing and testing prototypes, among other tasks. Here are some general responsibilities a mechanical engineer can have:

1. Design: This involves creating blueprints for new systems or machinery using CAD software. The complexity of the design would depend on the requirements of the project. This might range from a small component to a full-fledged machinery system.

2. Analysis and Testing: Mechanical engineers often have to analyze designs to ensure they meet standards and safety requirements. They might conduct computer simulations or physical tests to assess system performance and reliability, and then modify designs based on the test results.

3. Research: Many engineers spend a significant portion of their time researching new technologies, materials, or methodologies that can improve efficiency or solve specific problems in their field.

4. Project Management: This involves planning and overseeing projects to make sure they're completed on time and within budget. It could include coordinating with other team members, vendors, contractors, and clients, and managing resources.

5. Maintenance: For those working in a manufacturing or industrial context, maintenance of the machinery and systems could be a major part of their responsibilities, which includes monitoring systems and fixing any mechanical issues that arise.

As far as skills are concerned, successful mechanical engineers tend to have a strong foundation in physics and mathematics to understand the principles governing their designs. Problem-solving is crucial as is attention to detail, since even slight errors can lead to significant issues in a design. Moreover, skills in CAD software and other engineering tools are highly valued. Communication plays a key role as well, both for conveying design ideas and for project management. Lastly, creativity and innovation are invaluable for developing efficient and effective solutions to complex engineering challenges.
