Homework Statement a uniform steel ring 60" in diameter and weighing 600 lbs is lifted by three cables each 50" long attached at points A (90*) B (90*) C (120*) with a radius of 30". compute the magnitude of tension force in each cableHomework Equations all moment equations ft=maThe Attempt at...

nevermind you square them all, add them, then take the square root.

I have no idea. The last time i did vectors at least six months ago.

Homework Statement find the magnitude and angle of the moment moment=-2.8i-1.53j+2.24k force tension=2.4 kNHomework Equations rxf=rfsin(theta)The Attempt at a Solution i used the cross product to get i j and k tried sin and cos of vectors but didnt work. inverse tan of vectors won't give...
