In a power plant the high pressure turbine trips due to an unauthorised valve shutdown. What are
a) what is the angular acceleration of the turbine blade?
b) what is the distance travelled by a point on the rim of the turbine blade during the acceleration?
c) what is the magnitude of the net displacement of a point on the rim of the turbine blade during the deceleration?
If the turbines 65 cm diameter blades slow down from 3850 rpm to 0 rpm in 3.8 seconds.
