3. Część teoretyczna.

Dane:

P₁= 800 [N]

P₂= 1500 [N]

M_s= 120 [Nm]

S_r= 320 [Nm]

1.Równania równowagi.

∑F_ix = S_r - R_Bx = 0 R_bx = S_r =320 [N]

∑F_iy = P₁ + P₂ - R_A - R_By = 0

∑M_i = - P₁* 200 +R_By * 400 - P₂ * 550 = 0

R_By = 2582,5 [N]

2. Siły wzdłużne.

0 <= x <= 200,

N = 0

200 <=x <= 400,

N = S_r = 320,

400 <= x<= 550,

N = S_r - R_Bx = 0

3. Momenty gnące.

0 <= x <= 200

M_g =R_A * x

M_{g(x = 0)} = 0

M_{g(x = 0,2)} = R_A * 200 = -56,5 [Nm]

200 <= x <= 400

M_g = R_A * x - P₂ (x - 200) + S_r * 150

M_{g(x = 0,2)} = -8,5

M_{g(x = 0,4)} = - 225

0 <= x <= 150

M_g = - P₂ * x

M_{g(x = 0)} = 0

M_{g(x = 0,5)} = 225

4. Momenty skrecające.

0 <= x <= 200

M_s = 0

200 <= x <= 400

M_s = 120

450 <= x <= 550

M_s = 120
