A small ring is held stationary with three forces, A, B and C acting on it.
Force A= 85 nt /20 , Force B= 160 nt /150 . Angles are in degrees relative to the +x axis being 0.
Find the magnitude and direction of Force C.
A. The stationary ring is in equilibrium, therefore A+B+C=0
B. For an object in equilibrium, a polygon formed by adding all forces on it must be a closed polygon.
C. A polygon with three sides can be solved by ...
