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.
False - Inertia is NOT a force. Inertia is simply the tendency of an objects to resist a change in whatever state of motion that it currently has. Put another way, inertia is the tendency of an object to keep on doing what it is doing.. Mass is a measure of an object's inertia.
