Расчет колец

0 < α < θ

M = 0,5 ⋅ P ⋅ r ⋅ [ cos(α) / sin(θ) - 1 / θ ]

+ M_max = 0,5 ⋅ P ⋅ r ⋅ [ 1 / sin(θ) - 1 / θ ]    при α = 0, 20, 40 и т.д.

N = 0,5 ⋅ P ⋅ / sin(θ)

  - M_min = 0,5 ⋅ P ⋅ r ⋅ [ 1 / θ - ctan (θ) ]    под каждым грузом

   Радиальное перемещение в точках приложения груза
δ = P ⋅ r³ ⋅ [ 1 /sin(θ)² ⋅ ( 0,5 ⋅ θ + 0,5 ⋅ sin(θ) ⋅ cos(θ) ) - 1 / θ ] / (2 ⋅ E ⋅ J) (наружу)

Радиальное перемещение в точках α = 0, 20, 40 и т.д.
δ = P ⋅ r³ ⋅ [ 2 / θ - 1 /sin(θ) - θ ⋅ cos(θ) / sin(θ)² ] / (2 ⋅ E ⋅ J) (внутрь)
