These notes about mechanical assemblies have been developed with an interactive and didactic approach to facilitate the understanding of mechanical assemblies within the subject of Engineering Drawing. They are intended for application in several engineering degrees, including Electrical and Electronic Engineering, Mechanical Engineering, Dual Degree in Thermal Engineering, Mechanical Design Engineering, and Industrial Technologies Engineering.
The content is organized into key sections covering essential aspects of mechanical assemblies: General Principles of Representation, Demountable Joints, Permanent Joints (Welding and Riveting), Surface Finish, Dimensional Tolerances, Mechanical Transmission Components, and Bearings.
In addition to traditional theoretical content, multimedia resources—especially explanatory videos—have been incorporated to help students visualize individual parts, assembled systems, and their operation in real or simulated contexts. This interactive approach enhances spatial visualization skills, a fundamental competence in this field, and allows students to better interpret technical drawings and understand the relationships between components.
Furthermore, this methodology promotes active and autonomous learning, enabling students to progress at their own pace and reinforce their understanding through visual and practical examples, ultimately contributing to the development of key professional engineering skills.
