how to calculate the theoretical moment of inertia of disk. mass is 68.9 grams and diameter is 10.3 cm. use equation I=1/2mr^2
Homework Answers
I = mr^2 / 2
m = 68.9 g = 68.9 * 10^(-3) kg
r = 10.3/2 cm = 5.15 *10^(-2) m
I = 68.9*10^(-3 ) * (0.0515)^2 / 2 =0.0914 * 10^(-3) kg m^2 = 91.4 *10^(-6) kg m^2

1. Determine the moment of inertia of a 4-kg disk with 12-cm radius 2. Determine the moment of inertia of a 4-kg ring with a 10-cm inner radius and a 12-cm outer radius. Notice that even though both objects have the same mass and the same outer radius, they have different moments of inertia because their shapes are different! The ring will resist more when we try to change its angular velocity than the disk will.
