thanks a lot...im so stupid at times...by the way, i don't need to convert it to meters because MPa = N/mm^2.
but thanks a lot, i have wasted so many hours thinking on this and the error just was that i could use my calculator properly...lol
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...
I was just wondering if there were any applications of the equations
U= GMm/r. Which basically means we are not to involve anything on Earth's surface.
Thx
