A spherical navigation buoy is tethered to the lake floor by a vertical cable(Figure 1). The outside diameter of the buoy is 1.00 m. The interior of the buoy consists of an aluminum shell 1.0 cm thick, and the rest is solid plastic. The density of aluminum is 2700 kg/m3 and the density of the plastic is 210 kg/m3 . The buoy is set to float exactly halfway out of the water. Determine the tension in the cable.

Problem 2. (20 pts) As shown in the figure, uniform generation occurs inside the spherical core with a radius n due to reactive heating at a rate of q 10 W/m3. The thermal conductivity of the reactive material is 20 Wm. K. The spherical shell 1Sr is made of stainless steel (s.s.) with a thermal conductivity k2 -15 W/m K. Given 0.5 m and k2 72=0.6 m, water flows outside to cool the s.s. shell at To-25°C and h =...
