Engineering design
Engineering design is a central and challenging area of learning within engineering education. By carefully developing fundamental topics such as statics, strength of materials and dynamics, machine elements, materials testing, descriptive geometry and engineering drawings, students are prepared for subsequent professional activities.
The educational objective of the “Engineering Drawing” course is the presentation of specific applications and the use of real workpieces and standard parts. The intention is to teach technical communication skills and to develop the real-world drawing tasks from a wider technological environment.
