Уважаемые эксперты! Пожалуйста, ответьте на вопрос:
На однородный цилиндрический блок массой m2 и
радиусом R намотана невесомая нить, к свободному
концу которой прикреплен груз массой m1 . К блоку
крестообразно прикреплены четыре одинаковых
невесомых стержня, на которых закреплены
одинаковые грузы массой m3 на расстоянии x от
оси вращения. Грузы m3 можно считать
материальными точками. Трением в блоке можно
пренебречь. Найти зависимость ускорения a груза
m1 от расстояния x . Построить график этой
зависимости в интервале изменения x от R до 3R.
Ускорение свободного падения 2
g = 9.81 / м с .
R=0,1м; m1=4кг; m2=1кг; m3=2кг
