Задача №32.15

Условие

Груз подвесили сначала к пружине с жесткостью c1=2 кН/м, а затем к пружине с жесткостью c2=4 кН/м. Найти отношение частот и отношение периодов колебаний груза в этих двух случаях.

Решение




Предыдущая задача №14
Груз массы m1=2 кг, подвешенный к пружине, коэффициент жесткости которой c=98 Н/м, находится в равновесии. В некоторый момент к грузу m1 добавили груз m2=0,8 кг. Определить уравнение движения и период колебаний двух грузов.
Следующая задача №16
Тело массы m находится на наклонной плоскости, составляющей угол α с вертикалью. К телу прикреплена пружина, жесткость которой c. Пружина параллельна наклонной плоскости. Найти уравнение движения тела, если в начальный момент оно было прикреплено к концу нерастянутой пружины и ему была сообщена начальная скорость v0, направленная вниз по наклонной плоскости. Начало координат взять в положении статического равновесия.
