Answer:
1470kgm²
Explanation:
The formula for expressing the moment of inertial is expressed as;
I = 1/3mr²
m is the mass of the body
r is the radius
Since there are three rotor blades, the moment of inertia will be;
I = 3(1/3mr²)
I = mr²
Given
m = 120kg
r = 3.50m
Required
Moment of inertia
Substitute the given values and get I
I = 120(3.50)²
I = 120(12.25)
I = 1470kgm²
Hence the moment of inertial of the three rotor blades about the axis of rotation is 1470kgm²
Answer:
The radius of the earth is 6,371 km.
The average Earth-Sun distance is 152.09 million km
How many Earths would fit between Earth and the Sun if they are separated by their average distance? Approximately 11,936 Earths.
I didn't really understand the last part, but if you don't get a better answer please mark me as brainliest.
