Stud welding uses a type of flux called a ferrule, a ceramic ring which concentrates the heat generated, prevents oxidation and retains the molten metal in the weld zone. The ferrule is broken off of the fastener after the weld is completed.
Inertia is a nice and easy physics lessons for kids and children. In physics, inertia is part of Isaac Newtonâs First Law of Motion simply stating that a particular object at rest will stay in that state unless otherwise a force is put on it for the object to move.
inertia inÂ·erÂ·tia (Ä­-nÃ»r'shÉ) n. The tendency of a body to resist acceleration; the tendency of a body at rest to remain at rest or of a body in motion to stay in motion in a straight line unless acted on by an outside force. Resistance or disinclination to motion, action, or change. inertia. The resistance of a body to changes in its momentum. Because of inertia, a body at rest remains at rest, and a body in motion continues moving in a straight line and at a constant speed, unless a force is applied to it. Mass can be considered a measure of a body's inertia.
