Using 0 Moment to find a force.

  1. Mar 30, 2010 #1
    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??

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

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