Question:

A cup anemometer uses two 5-cmdiameter hollow hemispheres connected to two 15-cm rods, as in Fig. P7.91. Rod drag is neglected, and the central bearing has a retarding torque of 0.004 N⋅m. With simplifying assumptions, estimate and plot rotation rate Ω versus wind velocity in the range 0 < U < 25 m/s
