Une force de compression s'exerce sur un ressort hélicoïdal fortement hélicoïdal. The spring has middle diameter D, wire diameter d, and it consists of i turns. The total length of the spring is L. Determine the total deflection of the spring for the member model and one‑turn deflection for the solid model.
A structure is made of two trusses of unequal length, which are embedded into the hinge supports. The structure is loaded by concentrated force. le poids propre est négligé. Determine the relationship between the loading force and the deflection, considering large deformations.
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. le poids propre est négligé. The frequencies, mode shapes, and equivalent loads of this 5-DOF system are analytically calculated and compared with the results from RSTAB and RFEM.
