Question 176: Centre of Mass and Rotational Motion

Question

Moment of inertia of a square plate of side l about the axis passing through one of the corner and perpendicular to the plane of square plate is given by :

Accepted Answer

According to perpendicular Axis theorem.
I
x
+ I
y
= I
z
I
z
$$\Rightarrow$$ $${{m{l^2}} \over 3} + {{m{l^2}} \over 3}$$
$$ = {{2m{l^2}} \over 3}$$

Answer

$${{M{l^2}} \over 6}$$

Answer

$${M{l^2}}$$

Answer

$${{M{l^2}} \over {12}}$$

Answer

$${2 \over 3}M{l^2}$$
