Задача №37.39
Условие
Найти уравнение малых колебаний однородного диска массы M и радиуса r, совершающего колебания вокруг горизонтальной оси Oz, перпендикулярной его плоскости и отстоящей от центра масс C диска на расстоянии OC=r/2. К диску приложен вращающий момент mвр, причем mврz=m0sinpt, где m0 и p — постоянные. В начальный момент диску, находившемуся в нижнем положении, была сообщена угловая скорость ω0. Силами сопротивления пренебречь. Считая колебания малыми, принять sinφ≈φ.Решение
