Question

An airplane propeller is 2.18 m in length (from tip to tip) and has a mass of 102 kg. When the airplane’s engine is first started, it applies a constant net torque of 1950 N⋅m to the propeller, which starts from rest.What is the angular acceleration of the propeller? Treat the propeller as a slender rod.

    Answer:

    Explanation:

    Moment of inertia of propeller

    = (1/12) m l²

    =( 1 / 12) x 102 x 2.18²

    = 40.4 kgm²

    torque = 1950 N-m

    angular acceleration

    =  torque / moment of inertia

    = 1950 / 40.4

    = 48.26 rad / s²
