Subject: varying coefficients for "clamped," "pinned," and "free" end conditions Доброго вечера всем! Помогите, пожалуйста, разобраться со следующими терминами: "clamped" и "pinned".Предложение такое: Throughout this discussion of marine panel structures, formulas will appear that have varying coefficients for "clamped," "pinned," and "free" end conditions. И далее для контекста: The end condition of a panel is the point where it attaches to either a bulkhead or a stiffener. With composite structures, the actual end condition is usually somewhere between "fixed" and "pinned," depending upon the attachment detail. It is common practice for designers to perform calculations for both conditions and choose a solution somewhere in between the two. For truly "fixed" conditions, stress levels near the ends will be greater because of the resisting moment introduced here. For purely "pinned" conditions, deflections in the center of the panel will be greater. Подскажите, в чем тонкое различие между "clamped" и "pinned" в данном случае? Заранее огромное thanks! |

А где, собственно, слово "clamp" в приведенном отрывке? Я думаю, что "clamp" это синоним "fixed". "clamped" или "fixed"- фиксированный или жесткая заделка "pinned"- шарнирный или на шарнирной оси |
| Я тоже думаю, что это три сопроматовских случая заделки балки/фермы. |
