Statics: load supported on a wooden frame

[QUOTE="SoylentBlue, post: 6088127, member: 540681"] Now [B]that [/B]was an embarrassing error.:oops: OK, I now have the correct answer for IB. Next, we look at the top of the frame, examining DHC; If we sum the moments from point D, the moment caused by GH balances the moment caused by the load at point C, and we get the correct answer for the value of GH. So far so good. However, shouldn't we also be able to look at BDHC, and sum all the forces in either the x or y direction? If we look at the y direction, in that case we get an incorrect value of zero for GH. [B][B]ΣFy[/B]: Ay - (cos30)(IB) + (cos45)(GH) -150=0[/B] [B]Ay is in compression, pushing up; IB is in tension pulling down, GH is pushing up, and of course the 150 load pulls down. 324 - 174+.707GH-150=0 324-324 = .707GH[/B] This has to be an error in logic rather than a math error, right?
