So if I find the unit vector for CD, do I just add the coefficients of i and j together to make a force equilibrium equation? The unit vector for CD should be λAB=-3/5i+4/5j, correct?

Homework Statement The steel beam is supported by cables AB and CD and a ball-and-socket joint at O. The position of the vertical point load, P influences the reaction at O as well as the tension in each cable. First you need to derive the equations for the tension in cable AB, the tension in...
