[QUOTE="Phil Graham, post: 40339, member: 430"] Re: Line Array on Global Truss. Without knowing the centroid of the four boxes and the array flybar configuration, it is hard for me to agree with this statement. It might be a dead hang, it might not. Also, even if the front and back points have identical vertical loads, the shear-stress loading placed on the bolts below the cheeseboroughs (or on the truss) as a consequence of any adverse load on the array (e.g. doing a chinup from the bottom box of the array) would probably overwhelm something, in shear, in an emergency situation.
