Statics and Strength Theory

First cycle, Bachelor

The students are able to:
• Analyze systems of forces and calculate unknown forces by size and direction.
• To apply the equilibrium conditions in statically determined systems.
• Determine the existing internal forces in members, beams and frames.
• Examine the level of framework and determine the magnitude of the bar forces.
• Investigate friction between machine parts.
• Differentiate between shear and normal stresses and identify vulnerable areas in machine components.
• To apply the basic relationships of strength theory to simple machine parts and to perform cross-sectional dimensioning.
• Make essential statements on strength hypotheses.
