the moment of inertia I = kg m2. This may be compared with a solid cylinder of equal mass where I(solid) = kg m2, or with a thin hoop or thin-walled cylinder where I(thin) = kg m2. The moment of inertia of a hollow circular cylinder of any length is given by the expression shown.Click to see full answer. Keeping this in view, what is the moment of inertia of disc?We assume the moment of inertia of the disc about an axis perpendicular to it and through its centre to be known ; it is M R 2 / 2 MR^2/2 MR2/2, where M is the mass of the disc and R is its radius. Thus the moment of inertia of a disc about any of its diameter is M R 2 / 4 MR^{2}/4 MR2/4.Subsequently, question is, how do you find the moment of inertia of a rectangular plate? The Moment of Inertia for a thin rectangular plate with the axis of rotation at the end of the plate is found using the following formula: Ie=m12(h2+w2) I e = m 12 ( h 2 + w 2 ) , where: m = mass. h = height. w = width. In respect to this, how do you find the moment of inertia of a hollow cylinder? Explanation: Moment of inertia of cylinder is IC=12MR2. The moment of inertia of the removed part is Ih=12ma2. Volume of the cylinder is VC=πr2L. The volume of the “hole” vh=πa2L. Ih=12⋅a2MR2⋅a2=12a4R2M. What is D in parallel axis theorem?The parallel axis theorem states that if the body is made to rotate instead about a new axis z′ which is parallel to the first axis and displaced from it by a distance d, then the moment of inertia I with respect to the new axis is related to Icm by. Explicitly, d is the perpendicular distance between the axes z and z′
