Question

four disc each of mass M and radius R atte arranges as shown in fig. the moment of Inertia about yy' will bite​

Answer 1

Answer:

Answer is 3MR^2

Solution

first Calculate

ICm = MR^2/4 (Passing through center in plane )

parallel axis Theoram =2× MR^2

ICm = 4 × MR^2/4

Inet = 4Icm + 2MR^2

Inet = MR2 + 2MR2
