# Mechanics 2

ME-MEC2

3.0

## Offered by

Mechanical Engineering

## ECTS

5

### Prerequisites

MA-MEC1, ME-MEC1 or similar basic skills in statics and strength theory.

### Main purpose

The
aim of the course is that the student will be able to analyze stresses, strains
and deformations in structures in order to assess a machine construction in
relation to safety against permanent deformation and fracture

### Knowledge

The student acquires knowledge of mechanics in the following:

• ​Definition and determination of mechanical stresses and strains in materials.
• Analysis of planar stresses at combined loads, including the use of Mohr`s Circle.
• Use of Static yield and fracture criteria in dimensioning.
• Analysis of deformation in structures and calculation of statically indeterminate structures.
• Analysis and calculation of columns

### Skills

The student who completes the course acquires skills in:

• ​Defining and determining the stresses and the strains by axial load, torsion, bending and shear of a structure.
• Analyze planar stresses in structures with a combined load, both when calculating and when using Mohr`s Circle.
• Dimension static loaded machine structures including determine the safety to static yield and fracture.
• Determine the deformation of beams by integration of the beam differential equation and using superposition based on values from tables.
• Calculate reactions in statically indeterminate structures.
• Dimension simple centrally loaded columns.

### Competences

​After the course, the student must be able to:

• Analyze, evaluate and document a mechanical design in relation to its strength. In addition, the student will have the competence to develop his or her knowledge and skills in mechanics.

### Teaching methods and study activities

​The duration of the course is approx. 12 weeks with 4 lessons per. week. The total work load for the student is rated at 138 hours.
The form of teaching is class teaching with theory review combined with problem solving.
It is expected that the student between the lessons reads the literature used and solves assignments in study groups.
