A force F = 6.61×104 N and a couple moment M = 3.41×104 N·m are applied to the steel frame as shown. Assume L1 = 1.19 m, L2 = 3.59 m. The angle of the cable BC is indicated by the small triangle. What is the tension in the cable?

@rajat97  thanks for your help in advance

rajat97 · Answer

you're welcome and i've got the answer as T=1231.81 N
if it is right, please let me know

@GavinxFiasco

anonymous · Answer

unfortunately it isn't right

rajat97 · Answer

oh 
see what i did was that i balanced all the torques 
and i think i need to work on it

rajat97 · Answer

just wait for a few minutes

rajat97 · Answer

i took the wrong ref. point and now i am trying it with point A

anonymous · Answer

alright, take as much time as you need I'm trying to figure it out as well

rajat97 · Answer

now i've got the answer as 377.55 N

anonymous · Answer

still incorrect

rajat97 · Answer

wow

anonymous · Answer

ya, this questions been stumping me for quite a while now

rajat97 · Answer

i've got something new here and my answer is 521N
try try but don't cry

hmm.....

anonymous · Answer

I know , -.-'

anonymous · Answer

I can't tell what the moment is doing - is it trying to bend the beam down or pushing it to the left? :P

anonymous · Answer

I believe it is trying to bend the beam downwards or push down on it

anonymous · Answer

oh, derp, because of the cross beam.  Gotchya

anonymous · Answer

Ya aha

rajat97 · Answer

i"ve got another answer and i know its really irritating and my answer is 751.33N

anonymous · Answer

right or wrong at least you have answers - I'm still trying to set up the darn thing :/  ^_^

rajat97 · Answer

@AIITehMaffs what is your ref. point

anonymous · Answer

that's what I'm trying to figure out :/  I was thinking along the top beam, so the moment is equal to 3L1 cross Ty, but I'm pretty sure that wrong

anonymous · Answer

I know that's wrong, actually :P

rajat97 · Answer

look if you take the ref. point as the hinged point A, it will be benificial as the torque due to hinge forces will be seen as zero

rajat97 · Answer

so i did the same

rajat97 · Answer

do you have any idea ????
