No, a light bulb will not light if its metal tip rests on a metal casing. The metal tip of the light bulb needs to be connected to the electrical circuit in order for it to light up. Resting on metal casing would not provide this connection.
if i was to remove metal i would use pliers
Something I would run away from. Gun powder BURNS, it does not explode.
Refrigerators are usually made from iron, which is magnetic. As for the part it would be the refrigerators door or outer casing.
When a solid melts, it transitions into a liquid state. In the case of a lighter, the solid plastic or metal casing may melt when exposed to extreme heat, but the fuel inside (such as butane) would vaporize before the casing reaches its melting point.
Individuals may use metal cable ties for a variety of different reasons. One reasons would be the following: to bind loose objects together (eg. branches).
Using my rational, if a metal can be welded they probably make a wire for it. Cast Iron is the only one I would question.
You would have to cut it out with a blade or cable.
the reason the throttle would be sticking on your focus is that it (the actual unit) could be dirty. or the throttle cable could have dirt in its casing. what you need too do is remove the throttle cable and spray engine degreaser in the casing and hang it up too let the dirt and grime drip from it. be sure to use wd-40 to relubricate the cable. now as of the throttle body do the same thing. but use a non abrasive cloth and wipe the unit clean. make sure there is no dirt in any small cracks or crevises.
No, metal-free does not have the ability to remove chlorine from water. Metal-free is typically a product used to sequester or bind metal ions in the water to prevent staining or other issues. To remove chlorine from water, you would need to use a chlorine neutralizer or a water filtration system that is designed to remove chlorine.
dirt and gunk in linkages will cause accelerator to stick get some wd40 and spray on all moving parts if accelerator has a cable, renew cable as it will be clogged and rusted inside casing, making it stick
If your vehicle has a mechanical speedometer it might be your cable rubbing against its casing
