Задача №35.20
Условие
Три груза массы M1=20 кг, M2=15 кг и M3=10 кг соединены нерастяжимой нитью, переброшенной через неподвижные блоки L и N. При опускании груза M1 вниз груз M2 перемещается по верхнему основанию четырехугольной усеченной пирамиды ABCD массы M=100 кг вправо, а груз M3 поднимается по боковой грани AB вверх. Пренебрегая трением между усеченной пирамидой ABCD и полом, определить перемещение усеченной пирамиды ABCD относительно пола, если груз M1 опустится вниз на 1 м. Массой нити пренебречь.Решение
