(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

a) Find the reactions provided by the foundations at A and B.

b) Use the method of Resolution at the Joints to calculate the forces in all the members.

c) Which member will fail first and why ?

2. Relevant equations

ƩFx = 0

ƩFy = 0

ƩM = 0

3. The attempt at a solution

I am really just concerned with whether I have got the following correct. If I have, then I have grasped the concept if not then if someone could point me in the right direction and advise me on where to go next of what I am doing wrong I would be very grateful.

Horizontal Reaction Forces in the X direction at point A = 0

Vertical Reaction Forces in the Y direction at A = 4000N Upwards

Reaction Forces about the moment A at point B = 6000 Newtons Upwards

Forces in Member AC = 0N (0 + AC + AF = 0)

Forces in Member AF = 4000N in Compression (4000 + AC + AF = 0)

Forces in Member BK = 6000N in Compression (6000 + FBK.Sin(90) + FBE = 0)

Forces in Member BE = 0N (-FBE + FBK = 0)

Thanks
