# Mechanics Study plans 2016-2017 - BYG2251 - 10 ECTS

## Expected 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)

## Topic(s)

STATICS

- Statics basis
- Plane force systems - beams and simple frames
- Plane rod systems - Trusses

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
