It is possible to find the moment of inertia of an object about a new axis of rotation once it is known for a parallel axis. Sol: The given plate is symmetrical about the y-y axis, therefore \ = 150 mm. Moment of inertia is larger when an object’s mass is farther from the axis of rotation. This is also correct for a cylinder (think of it as a stack of discs) about its axis. To find \, we have to divide the whole Figure into standard areas.Įxample: Find the moment of inertia of a plate with a circular hole about its centroidal x axis as shown in Fig.8. that formula will then give the moment of inertia of a cube, about any axis through its center. moment of inertia calculation-namely, the moment of inertia of a thin circular ring about. Recall that in our derivation of this equation, each piece of mass had the same magnitude of velocity, which means the whole piece had to have a single distance.

Sol: The given I-section is symmetrical about the y-y axis, therefore, is termed the moment of inertia of the object, and is written. Moment of inertia of the entire circular section about the axis ZZ will be determined by integrating the above equation between limit 0 to R and it as displayed here in following figure.
