Задача №5.41
Условие
При взаимодействии с ледяным покровом ледокол рассматривается в равновесии под действием веса судна G, силы поддержания воды D, упора винтов R, а также сил, действующих со стороны льда в точке форштевня K: нормального давления N и максимальной силы трения F. Угол наклона форштевня φ=30°, коэффициент трения f=0,2. Известны значения G=6000 кН, R=200 кН, a=20 м, b=2 м, e=1 м. Пренебрегая дифферентом судна, определить вертикальное давление судна на ледяной покров P, силу поддержания D и расстояние ее от центра тяжести судна l.Решение
