Answer

$I_A=7.67Kg\cdot m^2$

Work Step by Step

The required moment of inertia can be determined as follows: We know that $I_G=m_1r_1^2+\frac{m_2l_2^2}{12}$ We plug in the known values to obtain: $I_G=10(0.5)^2+\frac{4(2)(1)^2}{12}$ $\implies I_G=3.1667Kg\cdot m^2$ Now $I_A=I_G+(m_1+m_2)d^2$ We plug in the known values to obtain: $I_A=3.1667+(10+4(2))(0.5)^2$ This simplifies to: $I_A=7.67Kg\cdot m^2$
