Find the moment of inertia of a disc of radius 0.4 m and mass 0.75 kg.

Answer:- Specified: –

A disc of radius 0.4 m and mass of 0.75 kg.

To Find: –

What is the moment of inertia?

Solution: –

Specified:

Radius = 0.4 m

Mass = 0.75 kg

Conferring to the question by using the formula we get,

I= mr²/2

where,

I = Moment of Inertia

m = Mass

r = Radius

Consequently, by putting those values we get,

=> I= 0.75 x (0.4)²/2

=> I= 0.75 x (0.4 × 0.4) /2

=> I= 0.75 x 0.16/ 2 =

=> I= 0.12/ 2 =

I = 0.06 kgm²

The moment of inertia is 0.06 kgm² .
