have uploaded the question on the web. Please have a look at:

I have tried doing this problem, but i am not getting the right answer. This is what i did:
y(unknown)=40cos60 = 7 mm
x (unknown) = 40 cos 30 - 20 == 14.641mm
Then
Pcompression = 2(75x7x(34.641/2)) + 2(((20x75)/2)(14.641)
= 40149 N
But the answer is somehow... 73.92 KN
Is there anything wrong with my calculations?
Thanks
