Therefore I would like to calculate the axial and radial force on the shaft, so I can select the right bearings.

The picture looks a as following: http://i39.tinypic.com/kd1naq.jpg

So I have a shaft, with a plate attached on it with a weight of 10kg. A load will be putted on the plate wit a weight of 37,5kg. Now I would like to calculate the axial and radial force on the shaft.

Sketch:

Sum Fx to A = o

Fxa = o

Sum Fy to A = o

(-375N x 0,625 x 0,3125) – (100 x (0,725/2)) + Fya x 0,725 = 0

-73,2 - 37,6 + Fya x 0,725 = 0

-110,8 + Fya x 0,725 = 0

Fya = 110,8 / 0.725

Fya = 153N

Som M t.o.v. A = o

M in a = 375 x (0,725 – 0,3125) + 100 x 0,3625

M in a = (375 x 0,4125) + 36,25

M in a = 191Nm

The shaft would have an axial force of F = 153 N and radial momentus of M = 191 Nm according to this calcuation.

Does this look ok, or should I calculate it completely differently?
