= 292 lbs. compression. 56.0 The stress in wire 1 upper to 2 lower is found by the method ofshears, using the principle that the vertical component of the stress inthe wire equals the shear. This is true because the chords of the trussare parallel and horizontal. The shear equals the loads to the… … 82 Art. 65 Wing Spar Fittings The stress in strut 2—2 is found by applying %V = 0 to joint 2 oflower wing. Stress in strut = 92 -j- 116 -f- 129 = 337 lbs. compression. The solution for stresses in members of panel 2—3 is similar to thatjust given for panel 1—2. Using the method of joints at station…
