my homework problem deals w/ rotation in x-y plane. so the tensor is only 2d. inertial tensor still seems obscure to me... my question for now is purely mathematical. assuming the basis are (x,y). I calculated the components of I, is the following correct?
[tex]I_{xx} = m_i y_{i}^{2}[/tex]
[tex]I_{yy} = m_i x_{i}^{2} [/tex]
[tex]I_{xy} = I_{yx} = - m_i x_i y_i [/tex]
for some reason my professor wrote...
[tex]I_{xx} = m_i x_{i}^{2} [/tex]
and I'm pretty sure its not right
