Mechanics 2

Code

ME-MEC2

Version

2.0

Offered by

Mechanical Engineering

ECTS

5

Prerequisites

The course ME-MEC1 or a course with similar basic skills in statics is completed.

Main purpose

That the student will be able to analyze stresses, strains and deflections in structures in order to assess a machine design in relation to safety against yielding and fracture.

Knowledge

The student will acquire knowledge in methods of analysis and calculation within mechanics in the following subjects:
* Stresses and strains in materials.
* Plane stress with the Mohr diagram, combined load.
* Static failure theories.
* Deflection of beams, statically indeterminate structures.
* Buckling of columns.

Skills

Following completion of the course the student will be able to,
* Calculate stresses and strains in materials from axial load, torsional load, bending, and transverse shear.
* Analyses of plane stresses from combined loads of a structure by calculation and by use of Mohr di-agram.
* Dimensioning static loaded machine components and determine the safety factor against static fail-ure
* Calculate deflections of beams by integrating the elastic line equation and by use of superposition and standard figures.
* Calculate reactions in statically indeterminate structures.
* Calculate for buckling of simple columns with a centrical axial load.
* Design and approve static loaded structures.

Competences

The student will gain competence to analyze, evaluate and document a mechanical design in relation to its strength.

In addition, the student will have the competence to self-expand his knowledge and skills in mechanics.
