Question

Theorem of perpendicular axis is used in obtaining the MOI of a
(I) Triangular lamina
(II) Square lamina
(III) Circular lamina
(IV) Semicircular lamina
Which one is correct answer​

Answer 1

Answer:

triangular lemina is the correct answer

Answer 2

Concept introduction:

Given that, A planar lamina's moment of inertia at an axis perpendicular to its plane (also known as the z-axis) is equal to the sum of its moments of inertia along any two axes that are perpendicular to one another and both lie in the same plane. Ix + Iy = Iz.

Explanation:

Given that,

We have to find, Theorem of perpendicular axis is used in obtaining the MOI of which of the given lamina.

According to the question,

Thin plate of triangular shape is called triangular lamina. Theorem of perpendicular axis is used in obtaining the MOI of a triangular lamina.

Final Answer:

(I) Triangular lamina
