Using 0 Moment to find a force.

[weedannycool]

how do you find a 0 moment on a system. for example if i had a block with two forces in tension either side and i know 1 tension value and i want to find the other which will cause zero moment at a point ( say O ). any ideas??

Thanks

please more expplaination

i'll draw a pic. i want to find T so there is zero moment at O. but the block is suported

hope you can understand that :/

Resolve the forces into components and sum the moments about point 0. You should end up with enough equations to solve for T.
