|Reactions are Va + Vb = 5t.
Let length of each member be x.
Moment atB = 4t * x - 5t * x + Va * 2x = 0.
Therefore 1t = 2Va.
Hence Va = 0.5t.

|Hello Ddendu can you tell me, why the x is multiplied with 4t, as it is 2x distance away from B.|
|Pradyumna Kumar Nayak said: (Apr 19, 2016)|
It is a perpendicular distance of line of force and point B. So only x is multiplied.

|Considering the joint A.
As Va = 0.5 T upward.
fac = 0 & fad = 0.5T compression.

How is EF=BC= X? Are all the members equal in a truss all the time?

|How it is compression. Show it will be .5 tension?|
|Tapas said: (Feb 22, 2019)|
When axial force moves towards the joint it is compression. As the reaction on the left side +ve so it is an upward reaction, so to balance it an equal downward force will be induced in the member AD. Hence both as the forces are moving towards the joint A hence the member AD is under compression.
