Can someone slove the fx and fy equations in the below questions solution in steps to how we got f1 and f2 values. Thanks.

Transcribed Image Text:An assembly consisting of tie rod (1) and pipe strut (2) is used to support an 80 kip load, which is applied to
joint B. Strut (2) is a pin connected structural A-36 alloy steel (E=29,000) pipe with an outside diameter of 8.625
in. and a wall thickness of 0.325 in. For the loading shown in figure, determine the facotr of safety with respect
to buckling for memeber (2)

Transcribed Image Text:Step 1
Given
Young's Modulus, E = 29000 Pa
Diameter = 8.625 in
Wall thickness, t= 0.325 in
Find
Factor of safety, FS

EF, = - F, cos (26.565°) - F2 cos (51.340°) = 0
EF, = F, sin (26.565°) – F2 sin (51.340°) – P = 0
