Основные расчетные формулы.

З

(1)

ависимость для наибольшего давления (Формула Нобля-Абеля):

P_m1/₁=+P_m1 (2)

P_m2/₂=+P_m2 (3)

А

(4)

(5)

затем из выражения (3) или (2) находим (₁=100;  ₂=200).

Для получения импульса считаем площадь под графиками зависимости P(t)

J_k1 = 228800 Н∙м

J_k2 = 228800 Н∙м
