Продолжаем вычислять моменты инерции плоской фигуры (см. другие лекции на эту тему). Выводим формулу для вычисления площади фигуры обходом по ее контуру. Показываем способы учета вырезов. Приводим формулы для вычисления моментов инерции. См. книгу автора "Maple и maplet. Решение задач механики", Лань, СПб, 2012
We continue to calculate the moment of inertia of a plane figure (see other lectures on the subject.) Derive the formula for calculating the area of ​​a figure crawl along its contour. Show ways to incorporate cut-outs. Here is the formula for calculating the moments of inertia. See the author's book "Maple and maplet. Solving mechanics", Lan, St. Petersburg, 2012
