In the example I described above, there is no clamped object.

This was created as the simplest example of adjustment from an applied Bolt Preload Force.

Adjustment is the contraction required at the center of bolt to achieve the pretension force entered.

Change the example above and let just one end have a Fixed Support and the other end have a spring to ground, with a 25000 N/mm stiffness. The spring represents the clamped object. Now the adjustment is 1 mm to compress the spring to 25000 N plus the 0.3457 mm to stretch the bolt.


If you apply an Adjustment instead of a Preload Force, you can find out the force in the bolt by plotting the Working Load.
