# A uniform square plate S (side c) and a uniform rectangular plate R (sides b, a) have identical areas and masses (Fig. 7.11).

Show that

(i) I _{xr} / I_{xs} < 1; (ii) I_{yr}/ I_{ys} > 1; (iii) I_{2R}/ I_{2s} > 1.

Answer :

According to question

Area of square=Area of rectangular plate

a) As

(as from diagram b<c)

b) (as from diagram a>c)

c)

So,

Let I_{1} and I_{2} be the moments of inertia of two bodies of identical geometrical shape, the first made of aluminum and the second of iron.

A circular disc A of radius r is made from an iron plate of thickness t and another circular disc B of radius 4r is made from an iron plate of thickness t/4. The relation between the moments of inertia I_{A} and I_{B} is

A hollow sphere, a solid sphere, a disc and a ring all having same mass and radius are rolled down on an inclined plane. If no slipping takes place, which one will
