 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 EulerBernoulli beam theory (the Engineer's beam theory)
 explain Navier hypothesis (cross sections remain planar and normal to the deformed centerline)
