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

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)

Step 1
Given
Young's Modulus, E = 29000 Pa
Diameter = 8.625 in
Wall thickness, t= 0.325 in
Find
Factor of safety, FS
Step 2
Solution

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

Note: Tension assumed in each truss member.
Solve these equations simultaneously to obtain:
