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.
