Question

A pilot had just bought a airplane and is double checking his engine to make sure it is ready for flight

His engine is idling at 200.0 rpm (Revolutions per min). it is know that his engine attains its lift off angular velocity at 2.800x10^3 rom after executing 1360 rotations.

A) For each of the quantities given in the above wuestion convert each to the appropriate metric unit, also assign them a correct variable name

B)With the pilots new plane, what is the propellers angular acceleration

c) given the propeller has a mass of 63.0 kg and is 5.4 m from end to end, find the net torque acting in the propeller.

D) Identify the rotational analogue, use this to determine the power output of the engine in full throttle in watts and in horse power

typo rom is RPM

Answer 1

Answer: this is a simple constant angular acceleration motion problem
