Re: nuts
Watching them do the wing snapping tests is painful for us engineering types.... but it HAS to be done , there is no other way to prove the wing will work to 150% of max load.
I got involved in some work a long time ago on some clever bods saying what we built should take the loads involved and we dont have to test...... it blew up... upon building a test rig we found it failed at 90% of max load because manglement ordered the wrong material(because it was cheaper).. not that it made much difference.. the thing still failed the load test when we tried again... 4inch I section beam sorted that one out....
