In the below picture, there is a grid of 0.8 kg point masses separated by a = 1.3 m. For the masses on the RIGHT with the axis of rotation on the center column of masses, what is the rotational inertia? Enter your answer to the tenth's place.
Homework Answers
here,
the mass of each object , m = 0.8 kg
a = 1.3 m
for the masses on Right
the rotational inertia about the axis of rotation , I = 3 * m * a^2 + 3 * m* a^2 + 3 * m * 0^2
I = 6 * 0.8 * 1.3^2 kg.m^2
I = 8.1 kg.m^2
the rotational inertia about the axis of rotation is 8.1
kg.m^2
