There are many tricks used for calculation of moment of inertia in rigid body dynamics. Different types of problems are asked every year based on moment of inertia in JEE Main, JEE Advanced and NEET. In the topic of Rigid Body Dynamics, most of the problems involve calculation of moment of inertia of the object in consideration so questions based on this concepts are essential to be covered in detail. In this video Ashish Arora Sir is explaining calculation tricks of moment of inertia of different objects in rotational motion based on mass distribution property.

For quick coverage of all concepts of Rigid Body Dynamics students can review this topic from Physics Galaxy checklist video of Rigid Body Dynamics available at below given links.

There are 5 Practice Quiz Questions based on concept of vertical circular motion explained in this video. Students are advised to solve below questions and find, out of given questions below which question(s) are given with wrong answer(s) and post your answer in the first comment in comment section. Correct answer with explanation will be shared in after two days.

(1) A thin square plate of mass M, edge length L is rotating about an axis passing through its center of mass, in its plane and at an angle 30° to one of the edge. If half of plate on one side of axis is removed, find moment of inertia of remaining part about this axis of rotation.
[ML²/24]

(2) Find moment of inertia of a Cylinder of mass M, radius R and length L is rotating about an axis of rotation passing through center of one of the circular face of cylinder and perpendicular to central axis of cylinder.
[(1/12)ML²+(1/4)MR²]

(3) A cone of mass M, base radius R and Length L is rotating about its central vertical axis of rotation with its base horizontal. If it is cut in two parts of equal mass M/2 by a horizontal plane parallel to its base and I1 and I2 be the moment of inertial of upper and lower parts of cone then find the ratio I1/I2.
[1/(2^(5/3)-1)]

(4) Find moment of inertia of a hemispherical shell of mass M, inner radius r and outer radius R about an axis of rotation passing through center and perpendicular to its base. (Calculate using the trick explained in above video)
[2M(R⁵ - r⁵)/5(R³-r³)]
(5) A plate of mass m having the shape of a right triangle of edge lengths a,a,a√2 is rotated about a given axis of rotation parallel to one side of length a and passing through the vertex where other side and diagonal intersect. Find moment of inertia of plate about this axis of rotation.
