Find the principal moments of inertia about the centre of mass of a flat
rigid body in the shape of an isosceles right angled triangle. What are the
principal axes of inertia.
2. Three equal masses are located at the point (a, 0,0), (0,0, 2a) and (0, 2a, a).
Obtain moments and product of inertia relative to the coordinate axis.
Also find the principal axis and principal moments of inertia.
Next Lecture's preview
In the next lecture we will start a new topic "Rotational Kinetic Energy of a
rigid body". We will derive its mathematical expression. The second topic will
be Equi-momental system. we will see some related examples at the end of
lecture.

The figure shows the side view of a portable traffic signal. The upper portion of the signal with attached frame has a mass of 90 kg with mass center at G. The signal and frame are hinged at point E and rest on a vertical post at H. In operation, member DEH is positioned vertically by means of the hand-operated winch so that the lights are directed to the left. Determine the necessary input force F that will just start to rotate the signal from its horizontal position. Note that handle A is rigidly attached to gear B. The dimension (AB) ̅=200 mm.
