Moment of inertia of a thin semicircular disc (mass = M & radius = R) about an axis through point O and perpendicular to plane of disc, is given by :
                                   
  • a)
     
  • b)
  • c)
     
  • d)
    MR2
Correct answer is option 'B'. Can you explain this answer?
Verified Answer
Moment of inertia of a thin semicircular disc (mass = M & radius =...
Mass of semicircular disc = M
Suppose there is a circular disc of mass 2M, then
Moment of intertia of circular disc = ½ (2M)R2
Moment of intertia of circular disc = ½ (2M)R2 = MR2
=> So, Moment of intertia of semi-circular disc = ½ MR2

Moment of inertia of a thin semicircular disc (mass = M & radius =...
Mass of semicircular disc = M

Suppose there is a circular disc of mass 2M, then

Moment of intertia of circular disc = 1/2(2M)R2

Moment of intertia of circular disc = 1/2(2M)R2 = MR2

=> So, Moment of intertia of semi-circular disc = (1/2)MR2
