Twenty equal measurements of the moment of inertia of the cranked shaft relative to the axis of rotation yielded the following results (in kgm2):

12.0	12.8	13.8	13.1	13.0
12.0	14.2	14.0	14.0	14.9
15.0	15.5	15.9	16.9	16.9
17.0	17.5	18.0	19.3	20.1

Find confidence intervals for the true moment value of inertia with a reliability of 0.95 and an average deviation from the average with a reliability of 0.99. Accept that the results of the measurements are distributed according to normal law.

moment of inertia of a rod

Starting with the formula for the moment of inertia of a rod rotated around an axis through one end perpendicular to its length (I=M ℓ² / 3), prove that the moment of inertia of a rod rotated about an axis through its center perpendicular to its length is I=M ℓ² / 12. You will find the graphics in Figure 10.12 useful in visualizing these rotations.

The parallel axis theorem relates Icm, the moment of inertia of an object about an axis passing through its center of mass, to Ip, the moment of inertia of the same object about a parallel axis passing through point p. The mathematical statement of the theorem is Ip=Icm+Md2, where d is the perpendicular distance from the center of mass to the axis that passes through point p, and M is the mass of the object.
