Задача №3.38
Условие
Для осмотра на плаву днища понтона водоизмещением D=2000 кН его носовая оконечность поднимается краном грузоподъемности P=750 кН. Принимая удельный вес воды γ=10 кН/м3, определить наибольший подъем днища над уровнем воды h, если понтон имеет форму прямоугольного параллелепипеда длины L=20 м, ширины B=10 м. Центр тяжести понтона C лежит посередине его длины. Точка K крепления троса подъемного крана и центр тяжести C находится на одинаковом расстоянии от днища понтона. (Водоизмещение судна численно равно его весу.)Решение
