Question

A uniform disc of radius 0.521m and unknown mass is constrained to rotate. What is the moment of inertia of the disc?

A) 0.142 kg·m²
B) 0.341 kg·m²
C) 0.524 kg·m²
D) 0.713 kg·m²

Answer 1

The moment of inertia of a uniform disc can be calculated using the formula I = (1/2) * m * r^2. However, since the mass of the disc is unknown, we cannot determine the correct answer from the options given.

Step-by-step explanation:

The moment of inertia of a uniform disc can be calculated using the formula:

I = (1/2) * m * r^2

Where 'm' is the mass of the disc and 'r' is the radius of the disc.

In this case, the mass of the disc is unknown, so we cannot calculate the moment of inertia without that information. Therefore, we cannot determine the correct answer from the options given.
