Question

Two barbells are sitting on the floor at the RWC. Both consist of a 10 kg bar with length 1.5 m, and two 25 kg plates. On the first barbell, both plates are located at the same end of the bar, while on the second barbell they are located at opposite ends. Which barbell has a larger moment of inertia?

A The barbell with both weights at the same end

B The barbell with the two weights located at opposite ends

C Both have the same moment of inertia

D Neither bar bell has a moment of inertia, since they aren't rotating

E There isn't enough information to tell, since the moment of inertia depends on the choice of rotational axis
