This deformation is irreversible, which means that thePessulum will fail. Once thePessulum enters the yield stage, it will produce permanent deformation. Once this limit is broken, thePessulum will enter the yielding stage from the elastic stage. Ut Pessulumcontracta est gradatim, ad effectum ad elasticæ Pessulum will approach a limit. Scire tantum opus est, ut in processus of futuit Pessulum, thePessulum is a kind of elastic part, and its elasticity will take effect. T dona nobis necesse est esse nimis secretior. In Mechanica evolvimus, hic terminus 'repraesentatur per iactabantur-accentus cogit. Due to the function of et seras, the material ofPessulums has two requirements, one is rigidity and the other is toughness, both of which are indispensable.Įt tubis ductilibus et omnia materiae habere unum in communi, hoc est, usque ad terminum accentus est a tolerantia. A tightenedPessulum should ensure that the upper and lower forces are balanced with each other. This force comes from the upward distributed force generated by the contact between the nut and the lower plane. ThePessulum rotates down along the thread, and a downward axial force is generated in the process of contact with the thread.Īt the same time, there is an upward force corresponding to the downward axial force. A Habes Pessulum is subjected to two forces, one is downward and the other is upward.
