Answer:
Explanation:
The body can be split into two parts
1 ) cylinder part of mass 7/8 x 64 = 56 kg of radius 20 cm
2 ) In the form of rod attached with cylinder having length 40 cm and mass
of 1/8 x 64 = 8kg
moment of inertia of cylinder
= 1/2 mr²
= .5 x 56 x ( 20 x 10⁻²)²
= 1.12 kg m²
moment of inertia of rods
= 1/3 ml²
= 1/3 x 8 x ( 40 x 10⁻²)²
= .4267 kg m²
Total MI = 1.5467 Kg m²
