the propeller of a World War 2 fighter plane is 2.1 m
in diameter.
Homework Answers
a)
1 rpm=0.10472 rad/s
angular velocity in radians per second
W=1280*0.10472 =134.04 radians/second
b)
radius of propellor
r=D/2=2.1/2 =1.05 m
Linear speed
V=RW=1.05*134.04
V=140.74 m/s
c)
centripetal acceleration
a=V2/r =140.742/1.05
a=18865.42 m/s2
