Finding transmitted forces in deformed model

[numanchris]

Hi!

I'm carrying out a buckling analysis and require to verify the buckling force by hand, to do this I (assume...) I'll need to find the force transmitted to a particular member (my geometry is a car chassis). I've been able to list the forces in a particular direction at every node, if I identify the force at a node which sits where the keypoint at the end of the member is placed, is this the force applied to that member?

I'm not sure if that is the right approach as I've applied 20,000N to the model and the nodal loads at the end of members is in the region of 10N?

Thanks!
