a) Explain (with derivations) why the moment of inertia for a rod of length L with mass M rotating around one of its ends is Cons ider a large wind turbine with 3 blades. Suppose each blade is 67 m long and has a mass of 22 tons. When a strong wind blows, it causes the blades to move by pushing with a force equivalent to 10' N acting through the centre of each blade. b) Determine the to tal torque acting on the wind turbine (ussume the wind force pus hes perpendicular to the blades) c) The operating speed of the wind turbine is 1 revolution every 10 seconds., By treating the blades as rods rotating around their ends (see part (a), determine the angular acceleration of the wind turbine, and thereby determine how long it takes to reach its operating speed (from a standing start). d) Once the wind turbine reaches its operating speed, it is connected to a electrical generator rhing running which keane it frm m acrelra furthar WAhat the nower outrut ef de
