the string masses are negligible and disregarding friction at the pulleys, each horizontal force on the ring will equal the weight on the hanger (with the hanger’s weight included). Fn=mn x g n=1,2,3 g=acceleration of gravity Standard unit of force: [m]=gr (gram mass) [F]=gmf (gram force) g=1 gmf / gr 1 gr of mass=1 gmf^(1) therefore, numerical values of mass and weight are identical. In static equilibrium, the force vectors must cancel out. (sum)Fn=0 On the…
