Question
Wind turbines are huge and getting bigger! Consider this
typical three-blade wind turbine configuration where
each blade has a mass and length of 21462 kg and 56
meters, respectively. Assume each is a uniform rod
attached at one end to the hub as show and determine (a)
the mass moment of inertia of the three blades in kg-m^2.
During a field test, starting from rest, the turbine hub
speed reaches a speed of 1.6 rad/s in 16.2 revolutions. (b)
Determine the average start-up angular acceleration in
rad/s/s. (c) Determine the average net torque observed
in N-m. CAUTION: For angular acceleration, report an
abundance of sig. figs.
Derive the ALGEBRAIC SOLUTION FOR (c) Torque in terms
of m, L, omega and delta_theta.
