Mass of the disc is equal to 500 g (m=500 g)
Radius of the disc if equal to 10 cm (r=10 cm)
1.
The diameter of the disc:
D = 1/4 (m) (r)^2
= 1/4 (500) x 10^2 g cm^2
= 12500 g cm^2
2.
The axis tangent to the disc and parallel to its
diameter:
= 1/4 (m) (r )^2 + m (r )^2
= 5/4 x 500 x 10^2 g cm^2
= 62500 g cm^2
3.
The axis through the center or the disc and
perpendicular to its plane:
= 1/2 (m) (r )^2 – ½ x 500 x 10^2 g cm^2
= 25000 g cm^2
