Question

Calculate the MI of a sphere rotating about an axis pasing through a pount of distance 0.1m from centre of sphere the mass of sphere is 5kg and radius of 0.2

Answer 1

Answer:

MI for sphere along axis passing through center= 2/5 MR^2

MI along axis parallel to it at a distance h is given by

MI'= 2/5 MR^2 + Mh^2

MI' = 2/5 (5)*(0.2)^2 + (5)* (0.1)^2

MI'= 2* 0.04 + 0.05

MI'= 0.08+0.05

MI'= 0.13 Kg m^2
