Answer:
Mass, M = 4.859 Kg
Explanation:
Given the following data;
Radius, r = 0.225 m
Moment of inertia, I = 0.123 kgm²
To find the mass;
Mathematically, the moment of inertia is given by the formula;
I = ⅖Mr²
Making M the subject of formula, we have;
Cross-multiplying, we have;
2I = Mr²
[tex] M = \frac {2I}{r^{2}} [/tex]
Substituting into the formula, we have;
[tex] M = \frac {2*0.123}{0.225^{2}} [/tex]
[tex] M = \frac {0.246}{0.050625} [/tex]
Mass, M = 4.859 Kg
