Just a tip with the inbuilt stress utlity (comosworks express). It only allows you to apply a pressure or a force uniformally distributed over an entire face. Since force x area = pressure, the two options are the same.

Since a spinner hitting a panel has completely different force pattern to that of a uniformally distibuted load, extrude a small face, similar in size to that of a spinner tip. I use 2mm x 2mm & extrude it 1mm. then select this face as the face to have the load applied to it. This results in esstianly the same as a point load, which is much more true to life.

As for restraints, the most accurate way would be to select your wheel/motor mounts, however if these aren't modelled in yet, just select the lower face of the sheet metal part.

Hope this helps. email me on mytqik at hotmail dot com if you have any more specific problems. I am online about 20hrs a day so you can MSN on the above address if you like.
