Ans 1.
A) From the given figure it is clear that the zero force members are FGF, FEF, FCH
B) Free body diagram:
Firstly, we use the equilibrium equations:
ΣV = 0 i.e., sum of all vertical forces = 0
Now, RA + RE-40 = 0
Or, RA + RE = 40 -----[1]
And as ΣMA = 0
RE *16 – 40 *12 = 0 -----[2]
Or, RE = 30KN
And RA = 10 KN
So, the FBD is:
C) Forces in member AB, BI and IH is calculated as below:

Here, tan Ɵ = 4/4 =1
Ɵ = 45 ͦ
Here also, we use the...
