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
  • 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
