    results don't match - bolt connectors

    Scott Nelson
      Hi,

      I'm a little confused by bolt connectors, they wont report reaction loads unless you activate strength data, but the bolt itself (dia. material, tpi etc) is irrelevant to the load placed on it.

      What I want to know is the reaction force seen at a bolt hole, but If I create a simple experiment (a 10m long beam bolted at each end with a single bolt to a fixed plate, and then apply a 10kn torgue at the beam center, I should see a reaction force at each bolt of 1000n (since each bolt is 5m from torque access. This is pretty simple math. But the bolt connector reports an axial load of 225kn at each bolt! This is off by a factor of 225. So, I'm sure (I hope) that cosmos is doing the math right - but it seems I'm not asking the right question?

      Any insight here?
