Задача №5.42
Условие
Груз Q может скользить по шероховатой вертикальной направляющей AB. К грузу прикреплен трос, несущий груз P. Пренебрегая размером блока D, определить:1) условие, при котором возможна зона застоя (геометрическое место возможных положений равновесия);
2) условие, при котором верхняя граница зоны застоя находится в положительной части оси y;
3) ординаты границ зоны застоя при Q=5 Н, P=10 Н, f=0,2, OD=10 см;
4) ординаты границ зоны застоя при Q=1,5 Н, P=10 Н, f=0,2, OD=10 см.
