About this course
Content
STATICS
- Statics basis
- Plane force systems - beams and simple frames
- Distributed loads - resultants
- Plane rod systems - Trusses
- Diagrams for normal forces, shear forces and bending moment
- 3-moment equation (basic, practical)
- Cables and ropes
STRENGTH OF MATERIALS
- Centroid of area and 2nd moment of area
- Stresses and strains (basic)
- Stresses in beams - simple cross-sections
- Torsion - circular cross sections
- Buckling
Learning outcomes
The course provides a basic introduction to statics and strength of materials, equilibrium and elasticity.
After completion the student should be able to:
Knowledge:
- explain how basic problems concerning statics and strength of materials can be resolved
- describe what is meant by static equilibrium
- explain different support conditions
- elaborate materials elasticity and stiffness, Hooke's law, and Young's modulus
Skills:
- assemble forces to a resultant and decompose forces
- find support conditions and joint forces
- calculate normal forces, shear forces, bending moment, torsion moment
- calculate bending, normal and shear stresses, and combining these
- calculate the centroid of area, 1st and 2nd moment of area and section modulus, and be able to apply the parallel axis theorem
General competence:
- know the Euler-Bernoulli beam theory (the Engineer's beam theory)
- explain Navier hypothesis (cross sections remain planar and normal to the deformed centerline)
Teaching methods
Lectures, assignments,academic supervision
This course is organized for web based students.
Nevertheless, there are two hours of training every week, mostly for the purpose of campus students who have not passed the subject of the previous academic year.
On the learning platform, there will be recordings from previous school years. This is complemented by pre-recorded video lectures, as well as examples and theory notes, which together with textbooks are the basis for understanding and ability to do exercises.
Mandatory work requirements:
10-13 compulsory exercises. All except 3 must be approved to get up to the exam. Additional calculation tasks, which are not mandatory, will also be available. These tasks are recommended.
Guidance is implemented through the learning platform, both synchronously using tools such as Collaborate, and asynchronously using "forum". There will be a plan for this on the learning platform. There will be 1-2 seminars in Gjøvik. These are not mandatory.
Estimated time spent:
Lectures etc.: 70 hours
Organized guidance, including the collections: 30 hours
Work with compulsory assignments: 100 hours
Other exercises and own exam preparation: 60 hours
