Question

The figure shows an isosceles triangular plate of mass M and base L. The angle at the apex is 90°.
The apex lies at the origin and the base is parallel to X–axis
32. The moment of inertia of the plate about the z-axis is

Answer 1

Answer:

Mass=m and Base=l

Angle at the apex is =90°

Find MI of theplane about the y−axis=?

Let, the axis of rotation pass through hypotenuse, considering rotation about hypotenuse you will see triangle.

Diagonal wisemI=ml

2/6

∴base=ml

2/24
