A structure is made of two trusses of unequal length, which are embedded into the hinge supports. The structure is loaded by concentrated force. Il peso proprio è trascurato. Determine the relationship between the loading force and the deflection, considering large deformations.
Una molla elicoidale strettamente avvolta è caricata da una forza di compressione. 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 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. Il peso proprio è trascurato. The frequencies, mode shapes, and equivalent loads of this 5-DOF system are analytically calculated and compared with the results from RSTAB and RFEM.
