The moment of inertia of an object with the radius of gyration and weight specified is 18.15 kg m².
Given that,
Radius of gyration k = 0.55 m
Weight = 600 N
We know that, weight = m* g
Let us consider, acceleration due to gravity = 10 m/s²
Substituting in the above formula, we have,
600 = m* 10
10 m = 600
Mass m = 60 kg
Radius of gyration is given by the formula, k = √(I/m)
where, I is moment of inertia
m is the mass of the body
Making I as subject, we have,
I = k² * m = 0.55² * 60 = 18.15 kg m²
