6.76 A wind turbine is operating in a 12 m/s wind that has a den- sity of 1.2 kg/m³. The diameter of the turbine silhouette is 4 m. The constant-pressure (atmospheric) streamline has a diameter of 3 m upstream of the windmill and 4.5 m downstream. Assume that the velocity distributions are uniform and the air is incom- pressible. Determine the force on the wind turbine. m P = Patm 4 Vz 4m 4 m Fx. Problem 6.76
For the position shown in the figure the spring is unstretched. The spring constant k, is designed such that after the system is released from rest, the speed of the mass is zero just as the 0.6 slug mass touches the floor. Find the spring constant, k and the maximum speed of block A and the location (distance above floor) where this occurs.
