A) \[\left( {{m}_{2}}+{{m}_{3}} \right)\frac{{{a}^{2}}}{4}\]
B) \[\left( {{m}_{1}}+{{m}_{2}}+{{m}_{3}} \right){{a}^{2}}\]
C) \[\left( {{m}_{1}}+{{m}_{2}} \right)\frac{{{a}^{2}}}{4}\]
D) \[\left( {{m}_{2}}+{{m}_{3}} \right){{a}^{2}}\]
E) None of the above
Correct Answer: A
Solution :
Moment of inertia of system about the axis which passing through\[{{m}_{1}}\] \[{{I}_{system}}={{m}_{1}}{{(0)}^{2}}+{{m}_{2}}{{\left( \frac{a}{2} \right)}^{2}}+{{m}_{3}}{{\left( \frac{a}{2} \right)}^{2}}\] \[{{I}_{system}}=({{m}_{1}}+{{m}_{3}})\frac{{{a}^{2}}}{4}\]You need to login to perform this action.
