ME-MEC1

2.0

## Offered by

Mechanical Engineering

## ECTS

5

### Main purpose

The course aims to provide the student with basic skills in statics and strength theory of materials to be able to analyze and dimension products, machinery, and equipment for production within the industrial field.

### Knowledge

The student acquires knowledge of basic statics within the following:
•  Description and calculation of force systems, forces, moments, couples and resultants.
• Formulation and description of static equilibrium, supports, free body diagram and equilibrium conditions.
• The application of join method and section method applied to plane trusses, force calculation in frames and machines.
• Definition and calculation of distributed loads, area centroid, external loads on beams, and internal forces in beams.
• Identification and formulation of equations for normal force, shear force and bending moment.
• Analysis of relationships between load, shear force and bending moment.
• Use of cross-sectional constants and material strength values in dimensioning.
• Identification and calculation of normal stress, shear stress, Von Misses stress and allowable stress.
• Description of dry friction.

### Skills

The student who completes the course acquires skills in:
• Making free body diagrams and formulate static equilibrium equations.
• Calculate reactions and determine internal forces in simple structures, which are statically determined.
• Dimension and design simple structures and choose materials based on the material's strength values.
• Provide calculation documentation in a technical report.

### Competences

After the course, the student must be able to:
• Perform analysis of mechanical loads as a starting point for the design and dimensioning of a simple product.
• Be able to take part in projects concerning simple design and dimensioning tasks.

### 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.
