A thin circular ring of a rectangular cross-section is exposed to external pressure. Stanovíme kritické zatížení a příslušný součinitel zatížení pro vzpěr v rovině.
A pipe with a tubular cross-section is loaded by internal pressure. This internal pressure causes axial deformation of the pipe (the Bourdon effect). Stanovte axiální deformaci koncového bodu trubky.
A quarter-circle beam with a rectangular cross-section is loaded by means of an out-of-plane force. This force causes a bending moment, torsional moment, and transverse force. Stanovíme celkový průhyb zakřiveného nosníku bez zohlednění vlastní tíhy.
A column is composed of a concrete section (rectangle 100/200) and a steel section (profile I 200). Je vystaven tlakové síle. Determine the critical load and corresponding load factor. The theoretical solution is based on the buckling of a simple beam. In this case, two regions have to be taken into account due to different moments of inertia and material properties.
A vertical cantilever with a square cross-section is loaded at the top by tensile pressure. Konzola je z izotropního materiálu. Calculate the deflection.
Tyč se čtvercovým průřezem je na svém horním konci vetknutá. The rod is loaded by self-weight. For comparison, the example is also modeled with the concentrated force load, the value of which is equal to the gravity. The aim of this verification example is to show the difference between these types of loading, although the total loading force is equal.
A cantilever beam with an I-beam cross-section of length L is defined. The beam has five mass points with masses m acting in the X-direction. Vlastní tíhu zanedbáme. The frequencies, mode shapes, and equivalent loads of this 5-DOF system are analytically calculated and compared with the results from RSTAB and RFEM.
Dokažte, že spojení různých rozměrových prvků nemá vliv na výsledky. A cantilever with a rectangular cross-section is fixed at one end and loaded at the other by concentrated forces. Neglecting its self-weight and assuming only small deformations, determine the cantilever's maximum deflections.
