The figure below shows an equivalent single degree of freedom (SDOF) model of a wind turbine. The rotor and nacelle system has a combined mass M = 200 kg and the per unit length of the tower is m = 10 kg/m. Assume the tower to be a uniform beam having length L = 30 m, second moment of area I = 10 m, Young's modulus E = GPa. Moreover, suppose that the rotor system has an eccentricity e = 1 m and an unbalance mass of mo = 10 kg. Considering the wind turbine damping coefficient 181774 N.s/m, obtain the steady-state response amplitude of the tip (i.e. steady state of response z (t) when the blades are rotating at fN = 235 rpm. 0.156 mm 0.035 mm 0.006 mm 0.078 mm 0.281 mm 00000

Question
The figure below shows an equivalent single degree of freedom (SDOF) model of a wind turbine. The rotor and nacelle system has a combined mass M = 200 kg and the mass per unit length of the tower is m = 10 kg/m. Assume the tower to be a uniform beam having length L = 30 m, second moment of areaI = 10 m, Young's modulus E = 70 GPa. Moreover, suppose that the rotor system has an eccentricity e = 1 m and an unbalance mass of mo = 10 kg. Considering the wind turbine damping coefficient e = 181774 N.s/m, obtain the steady-state response amplitude of the tip (ie. steady state of response z (t)) when the blades are rotating at ? = 235 rpm. 0.156 mm 0.035 mm 0.006 mm 0.078 mm 0.281 mm O000O
