Learning outcome
Students must develop an understanding of concepts and terminology related to mechanical systems. The students must have an understanding of the technological principles that apply when a mechanical function is to be designed into a product. An understanding of how forces and moments act in products and mechanisms. The students must gain an understanding that materials in themselves are a limitation and an opportunity when designing mechanical systems. The students must understand the effect and use of various mechanical components and how such components can be used in a design process. The students must be able to choose different solutions and components with the intention of being able to design mechanisms of different types. The students must be able to carry out simple analyzes of mechanisms and movements. This subject should provide a basic understanding and knowledge of the integration of mechanical functions during a design process
Learning methods and activities
Lectures are primarily conducted in the laboratory or in adjacent areas. All lectured material is available as short video clips that students can review as needed. The course is relatively lab-intensive.
The course is divided into modules, with each module including the following components:
- Lectures and Video Lectures: Short sessions, maximum of 30 minutes.
- Exercises and/or Lab Exercises: At least one mandatory exercise or lab exercise per module.
- Student-Active Learning: Supported by student assistants or peer evaluation systems.
- Practical Problem-Solving Focus: Learning is always connected to practical problem-solving, so there is minimal delay between learning and engaging in exercises and/or lab activities.
- Group Exercises and Lab Activities: Exercises and lab activities are conducted in groups.
- Guidance and Solutions: Exercises and lab tasks are meant to be guided throughout, with solution suggestions made available once the submission deadline expires.
- Mandatory Evaluation: Exercises and lab tasks are mandatory and graded as Pass/Fail. Extensions are generally not granted, though in special cases they can be arranged with the course instructor.
- Passing Requirement: 80% of exercises/lab tasks must be approved before the exam.
- Point System: A point system is established for lab activities and submission tasks.
- Exam Eligibility: 80% of exercises/lab tasks (points) must be approved to be eligible for the exam.
- Final Exam: A 4-hour written exam, using Aid Class C.

Further on evaluation
Students are divided into groups. (Group allocation is conducted at the start of the semester as a program-wide activity and is therefore not specific to this course.) Much of the work in this course is conducted in groups. A work log must be submitted with each assignment.
All modules include one or more mandatory activities to be performed in groups immediately following the lecture/instruction. These activities may involve a required submission or a lab exercise (where the submission is a lab report or solution to the assignment). Submissions have a one-week deadline following the lecture. A point system is in place, where more challenging or extensive tasks yield higher points. Students may submit after the deadline; however, late submissions do not earn points.
For exam eligibility, 80% of the mandatory assignments must be passed. Students slightly below the 80% threshold may still be permitted to take the exam but will need to complete a separate oral examination at the end of the semester.
The final exam is a 4-hour written, individual exam administered via Inspera. Permitted aids are in accordance with Aid Code C (see "Innsida" for more information):
- Pre-specified and/or printed resources
- Basic calculator
