Problem Statement:
The assembly shown is symmetric about the line along which the force F is applied. The parts are close-fitting (i.e. the clearance between the parts when assembled may be assumed to be zero). Find the following stress values if the joint is loaded with a force of F = 27 kips. For each case, make a sketch that illustrates the relevant stress area.
(a) The normal stress in the stem of part 1
(b) The normal stress in the stem of part 2
(c) The shearing stress in the tabs of part 1
(d) The shearing stress in the tabs of part 2
(e) The bearing stress between the tabs of parts 1 and 2
(f) The normal stress in part 1 at the cross-section indicated by the dotted lines.
Answers:
(a) σstem1 =
(b) σstem2 =
(c) τpart1tabs =
(d) τpart2tabs =
(e) σbearing =
(f) σpart1section =
