Learning activities:
The material is presented through lectures, supported by course literature. The theory is being applied to practical engineering design tasks through supervised problem-solving. A certain amount of time is devoted to the application of Finite Element Modeling (FEM) - software training.
Teaching support:
Assistant teacher and lecturers will be available for supervision during office hours.
Syllabus:
Hibbeler RC, Engineering Mechanics: Statics in SI Units, 14th Edition. Reading list and lecture notes will be handed out during the course.
Prerequisites:
FYS110 TBM120, (or corresponding previous knowledge)
Recommended prerequisites:
TBM120, TBA222, TBA223 and TBA224 (or corresponding previous knowledge);
Mandatory activity:
Delivery of assignments during the course.
Assessment:
3.5 hour written examination. Mandatory assignments must be approved in order to take the exam.
Nominal workload:
A total of approx. 250 hours of work is required, ie 8 hours of work must be expected per week in addition to the structured teaching.
Entrance requirements:
Special requirements in Science
Reduction of credits:
5 credits overlapping with TBA320 (15 credits) only for the accademic year 2021-2022.
Type of course:
Lectures: 50hours (4 hours per week). Exercises: 30 hours (2 hours per week).
Examiner:
The external and internal examiner jointly prepare the exam questions and the correction manual.
