The steel ring has a weight W=0.5 N and is suspended on the surface of the water (p=1,000 kg/m³, µ=0.001 kg/(m s)). If it takes a force of P = 0.55 N to lift the ring free from the surface, Problem 3.2.4 determine the surface tension of the water, o. Assume a wetting angle of 0 degrees. The radius of the ring is R=50 mm, and the cross-section of the ring is circular with a radius r=2 mm. 50 mm 01_PROB_76-77
