Moment of Inertia

Inertia can be termed as a resistance offered by a body to change its state. A rigid body initially at rest will apply resistance when acted by an external force that tends to change its state of rest or velocity, or a body initially at motion will provide resistance in changing its state of velocity or motion for coming to a state of rest. In other words, Newton's first law of motion describes the law of inertia of a rigid body.

Wind energy is gaining increased attention, generating an increased interest in windmill technology. Because windmill blades (vanes) rotate about a central axis, one of the most important physical properties of a windmill is its moment of inertia. Given is a picture of a typical windmill, where the geometry and center of mass of one of the vanes is illustrated. The mass of each vane is 411 kg. The distance from the center of mass of the vane to axis B is ?1=2.85 m. The distance from the center of mass of the vane to the center of the windmill hub is ?2=4.42 m. If the moment of inertia of a vane about axis A is 445 kg·m2 and about axis B is 10800 kg·m2, calculate the moment of inertia ?total of the entire assembly about the axis that passes through the windmill's hub and is perpendicular to the screen. (Ignore the hub and assume the vanes are flat.)
The uniform rod of mass M and length L rotates in the plane of the figure about an axis through one end. As the rod swings through its lowest position, it collides with a putty wad of mass m, that sticks to the end of the rod. If the rod's angular speed just before collision is w, a) what is the angular speed of the rod-putty system immediately after collision? Rotation axis Rod b) What is the change in the kinetic energy of the rod-potty system (immediately before to immediately after the collision)? Does the kinetic energy increases, decreases, or remains the same? Provide your answers symbolically.
