Question

4. (20 pts) Curling is clearly the most exciting sport on Earth. Lets pretend that the bottoms of curling stones are perfectly flat, round, and 12 cm in diameter. Lets also assume that the layer of water overlying the ice is 0.5 mm thick. There probably isnt pressure melting, but we will still assume the water is 4°C, at which temperature the dynamic viscosity is 0.0015 N-s/m2. a) What force must be applied to the side of the stone in order for it to ou ду b) What if they wanted to make a Summer Olympics version of curling, by playing on a travel at a constant speed of 1.1 m/s. Report your answer in BOTH newtons and pounds. layer of oil instead of water? At 20°C, SAE 10 oil has a dynamic viscosity of 0.079 N-s/m2. How thick would the oil need to be in order to match the shear stress you just calculated for the winter version of the sport?
