This backhoe trailer was used to test several wing truss and tail boom mock-up components. It was also used as an anvil to hammer out wing trailing edges. It's a handy work bench. The wing strut mock-up is attached, at one end, to the top of the A-frame. The other end is attached to the wing truss mock-up. This strut mock-up was plenty strong enough to handle the 6.7-G tensile load when the wing truss mock-up was tested. Tomorrow we plan to see how much of a compressive load (for negative G's) it will withstand. The steel strut mock-up dimensions (our best estimation) are: 1-3/16-inch OD, 0.060-inch wall thickness and 85 inches long. It is pinned at both ends. Anybody want to tell me how much force it will withstand?IMG_20190712_103136480.jpg
