The figure shows an isosceles triangle 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.

The moment of inertia of the plate about the `z-`axis is

A

`(ML^(2))/(6)`

B

`(ML^(2))/(8)`

C

`(ML^(2))/(24)`

D

none of these

Text Solution

Verified by Experts

The correct Answer is:
C

From `_|_` axis theorem
`I_(z) = I_(x) + I_(y)`
`I_(y) = I_(z) - I_(x) = (mL^(2))/(6) - (mL^(2))/(8) rArr I_(y) = (mL^(2))/(24)`.

A uniform rectangular plate has side length l and 2 l . The plate is in x - y plane with its centre at origin and sides parallel to x and y axes. The moment of inertia of the plate about an axis passing through a vertex (say A) perpendicular to the plane of the figure is I_(0) . Now the axis is shifted parallel to itself so that moment of inertia about it still remains I_(0) . Write the locus of point of intersection of the axis with xy plane
