Answered Properly (question no 3)
If hilok, NAS1436-4 has been chosen as a repair fastener, howmany fastener is required to be installed past the one side ofcut-area?
Analyze the single fastener ability to carry the load (loadcarrying capacity) if the additional following data is givenassuming edge margin and spacing is maintained as per StructureRepai Manual (SRM) standard: -
Shear allowable of fastener material = 67 ksi
Bearing ultimate of adjacent material (Al 7075-T6) = 127ksi
Shear allowable of adjacent material (Al 7075-T6) = 42ksi
Question 3 (20 Marks)
Design your repaired stiffeners or parts i.e. L-angles bysketching them in details with proposed installed fasteners areillustrated using standard drawing symbols with reference to sideview cross-sectional projection (aft looking forward viewonly).
