A closely coiled helical spring is loaded by a compression force. The spring has middle diameter D, wire diameter d, and it consists of i turns. Celková délka pružiny je L. Determine the total deflection of the spring for the member model and one‑turn deflection for the solid model.
Silnostěnná nádoba je zatížena vnitřním tlakem tak, že nádoba dosáhne pružno-plastického stavu. While neglecting self‑weight, the analytical and numerical solutions for the radial position of the plastic zone border (under the Tresca hypothesis) are determined and compared.
Konzola je plně fixována na levém konci a zatížena příčnou silou a normálovou silou na pravém konci. The tensile strength is zero and the behavior in the compression remains elastic.
