A Giant Frisbee. A solid copper disk of radius 10.50 m is launched toward the sun like a gigantic Frisbee with a constant linear velocity of 350 m/s and a rotation rate of exactly 438.7 rpm about its central axis. At the time of launch, the disk was very cold (-191.1 C). As it approaches the sun, however, it will get very hot. You and your team have been brought in to determine whether the increased temperature will affect the motion of the disk. (a) Will the rate of rotation be affected when the disk becomes hot? If so, how and why? (b) What will be the rate of rotation (in rad/s) when the copper disk reaches a temperature of 785.9 C? There are no external torques acting on the disk.

Hot gases are exhausted from a factory through a stack that is 20 m tall and 2.5 m in diameter. The outer surface temperature of the stack is measured to be 50°C on a day when the surrounding air temperature is 20°C and the wind is blowing at 2 m/s. The emissivity of the stack is 0.9 and the effective sky temperature (for radiation exchange between the stack and the open sky) is -10°C. Determine the total rate of heat transfer from the stack. Thermal properties can be evaluated at an air temperature of 35°C. *** Note: you must validate that your analysis is applicable to this system *** h = 20 m T_{sky} = -10°C v = 2 m/s T_{\infty} = 20°C
