In psychology, mechanical solution refers to a problem-solving method that relies on applying learned rules or procedures without necessarily understanding the underlying principles. This approach is characterized by a trial-and-error process, where the individual tries various solutions until a correct one is found.

Mechanical engineering is one of the broadest engineering disciplines—offering opportunities to specialize in areas such as robotics, aerospace, automotive engineering, HVAC (heating, ventilation, and air conditioning), biomechanics, and more. Mechanical engineers design, develop, build, and test.
