Homework Statement
Four 3 kg masses are aligned in a square, 8 meters on a side.
a- find the moment of inertia at the center, along an axis running perpendicular to the paper.
b- Find the moment of inertia along a line that passes through the center in the plane of the paper.
c- Find the moment of inertia of the system at mass 'c' ( mass in the bottom right corner) along an axis running perpendicular to the page.
Homework Equations
I = summation mr^2
The Attempt at a Solution
a- 4 ( 3 kg)(8m)^2 /2 = 384 kg m^2
b- 3 kg ( 4 ( 8.00 m ^2/2) = 48 kg m^2
c- 3kg ( 4 ( 8*8* 11.3 m ) ^2 = 6276218 kg m^2? I am obviously not setting this up correctly...
