stress analysis force question.

new to the Stress analysis environment and I am wondering, if you specify a force of say 1000 lbs and place the force arrows on 4 different rest surfaces, is that 4000 lbs or 1000 divided by 4?

thanks in advance

With 4 forces, 1000N each, included separately (select the face, then apply):

One force 1000N, in every faces.

One force, 4000N, in every face.

Although the different results, I think the forces are distributed in each face.

(I am really scared with these differences)

I found out the reason for the differences:
I have designed the 4 blocks asymmetric.

 


The results with the 4 blocks symmetric:

1000N applied in each face separately

4000N applied to all faces at the same time:

So, watch out with the asymmetric designs!
