l cricket 12:56 PM a session.masteringphysics.com C Exercise 9.32 MasteringPhysics I of I Constant u are a project manager for a manufacturing One of the machine parts on uniform rod that is 60.0 cm long and has mass 0.200 kg Part A company the assembly line is a thin, What is the moment of inertia of this rod for an axis at ts center, perpendicular to the rod? Express your answer with the appropriate units. IValue Units Submit Request Answer Part B One of your engineers has proposed to reduce the moment of inertia by bending the rod at its center into a V-shape, with a 60.0 angle at its vertex. What would be the moment of inertia of this bent rod about an axis dicular to the nlane of the Var ire vertey?

Explanation / Answer

a)

Moment of inertia is

I=mL2/12 =0.2*0.62/12

I=6*10-3 Kg-m2

b)

Moment of inertia

I=(1/3)(m/2)(L/2)2 +(1/3)(m/2)(L/2)2=mL2/12

I=0.2*0.62/12

I=6*10-3 Kg-m2
