I1 + I2 = [ (1/2) M1 * R1^2 ] + [ M2 * R2^2 ]
= (1/2)(6)(.1^2) + (2)(.5^2) = .53
Moment of inertia is a measurement of an object's resistance to rotational motion. It is calculated by taking into account the mass of an object and its distribution in relation to its axis of rotation.
Moment of inertia measures an object's resistance to rotational motion, while mass measures its resistance to linear motion. In other words, moment of inertia takes into account the distribution of an object's mass, while mass does not.
The factors that affect moment of inertia include the mass of the object, the distribution of the mass in relation to its axis of rotation, and the shape of the object. The farther the mass is from the axis of rotation, the larger the moment of inertia will be.
Moment of inertia is used in physics to explain how objects rotate around an axis. It is an important concept in understanding rotational motion and is often used in equations to calculate torque and angular acceleration.
Torque is the force that causes an object to rotate around an axis. It is directly proportional to the moment of inertia, meaning that the larger the moment of inertia, the more torque is needed to produce a given amount of angular acceleration.
