Рассмотрим соединение труб строительных лесов, подверженное действию осевой силы и момента. Self-weight is not considered. The material of the tube is idealized as perfectly rigid. All geometrical non-linearities are ignored. Determine the angle of deflection.
Докажите, что соединение различных размерных элементов не влияет на результаты. A cantilever with a rectangular cross-section is fixed at one end and loaded at the other by concentrated forces. Neglecting its self-weight and assuming only small deformations, determine the cantilever's maximum deflections.
