Answer:
The moment of inertia will be increased by a factor of 1575
Explanation:
Let the moment of inertia of a wheel be given as;
where;
I is the moment of inertia of the wheel
m is mass of the wheel
r is radius of the wheel
when the mass is increased by a factor of 7 and the radius is increased by a factor of 15
![I_1 = \frac{1}{2}mr^2\\ \\I_2 = \frac{1}{2}(7m)(15r)^2\\\\I_2 = \frac{1}{2}(7m)(225r^2)\\\\I_2 = 7\times 225[\frac{1}{2}(mr^2)]\\\\I_2 = 1575[\frac{1}{2}(mr^2)]\\\\Recall, \frac{1}{2}(mr^2) = I_1 \\\\I_2 = 1575 I_1](https://tex.z-dn.net/?f=I_1%20%3D%20%5Cfrac%7B1%7D%7B2%7Dmr%5E2%5C%5C%20%5C%5CI_2%20%3D%20%5Cfrac%7B1%7D%7B2%7D%287m%29%2815r%29%5E2%5C%5C%5C%5CI_2%20%3D%20%20%5Cfrac%7B1%7D%7B2%7D%287m%29%28225r%5E2%29%5C%5C%5C%5CI_2%20%3D%207%5Ctimes%20225%5B%5Cfrac%7B1%7D%7B2%7D%28mr%5E2%29%5D%5C%5C%5C%5CI_2%20%3D%201575%5B%5Cfrac%7B1%7D%7B2%7D%28mr%5E2%29%5D%5C%5C%5C%5CRecall%2C%20%5Cfrac%7B1%7D%7B2%7D%28mr%5E2%29%20%3D%20I_1%20%5C%5C%5C%5CI_2%20%3D%201575%20I_1)
Thus, the moment of inertia will be increased by a factor of 1575
