Uma força concentrada é aplicada durante um curto período de tempo no centro de uma viga de apoio simples. Considering only the small deformation theory and assuming that the mass of the beam is concentrated at its mid‑span, determine its maximum deflection.
A placa retangular simplesmente apoiada é sujeita a diferentes tipos de carga. Assuming only the small deformation theory and neglecting self-weight, determine the deflection at its centroid for each load type.
Na extremidade superior, está fixada uma barra com uma secção quadrada. 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.
