Podrobný popis

1. Forces
■ Definition of the force
■ Ground reaction force
■ Forces acting in the same line of action. Resultant. Reaction.
■ Concurrent coplanar force system
■ Nonconcurrent coplanar force system
■ Static moment of the force
■ Couple
■ Parallel forces

2. Cross section properties
■ Centre of the gravity of the prismatic bar
■ Centre of the gravity for special shape area
■ Moments of inertia of area
■ Parallel axis theorem - Steiner´s rule
■ Principal central axes of inertia
■ Radius of inertia - ellipse of inertia

3. Beams
■ Supports of the beam
■ Reactions
■ Simply supported beam
■ Two simplest and the most important examples
■ Cantilever
■ The simply supported beam with overhanging ends
■ Differential relationship among the load, the shear force and the bending moment
■ The beam loaded by a moment
■ The continuous beam with the hinge
■ The inclined support
■ The inclined beam

4. Trusses
■ Definition of the truss
■ Evaluation of the internal forces - the nodal method
■ The cross-cut method for the evaluation of the internal forces in the truss

5. Frames
■ Definition of the frame
■ Three-hinged frame

6. Curved beams and arches
■ Internal forces
■ Three-hinged arch loaded by a uniformly distributed vertical load
■ Three-hinged arch with tie

7. Orthogonally loaded frames
■ Simple orthogonally loaded frame
■ The systems of orthogonally loaded frames
