The radius of the disk is R, and the mass of the disk is M. Using the parallel axis theorem and theequation for the moment of inertia of a disk about its central axis developed in the previous example, Eq. (8), the moment of inertia of the disk about the specified axis is Fig.
Short Circuits. Short circuits are the second most common reason for breaker tripping and are a more serious concern. Short circuits occur when the black hot wires inside your electrical service panel come in contact with either other hot wires or neutral wires.
The way to reverse this is by either pulse charging the battery or by slow trickle charging the car battery. Sulfation may eventually cause the active material on the lead plates to break off and fall into the bottom of the cells which eventually will cause a short circuit as the material builds up in the bottom.
