Ok this is my working out Members GE, FD, EF Thanks mathmate.

Not sure what you mean by that :S. I've calculated both CD and BD and you were right they were the same except BD was a tensile force. How do I go about proving BE with the 10kN load on the E joint? Same for the D joint. Regards.

Wow 2/5 done preety happy. I am just not sure what I am supposed to do when the 10kN downward forces are put onto the joints? Say on Joint E a 10kN force is applied how would I go about finding GE or EF? Would they be the same? Like you said earlier CD=AC so how could I find member FD? Thanks a...

Here is my attempt at joint A to find AB and AC. I used trigonometry which is allowed by our school. im probably wrong but :( Thanks for your help mathmate.

Thanks mathmate. For question 1 i got 45kN for the Left support and 40kN for the right. But now I am not too sure what to do for the 2nd question Anyone got any ideas?

Sorry for double post But I really need help for this. Anyone have any assistance?
