What other item of stock can be measured with a sheet metal gage?
In addition to sheet metal, a sheet metal gauge can also be used to measure the thickness of other materials such as plastic sheets and non-ferrous metals like aluminum and copper. These materials can come in various thicknesses, and the gauge helps ensure proper specifications for manufacturing and fabrication processes. Additionally, some gauges may be used for measuring the thickness of certain types of wood or composite materials in specific applications.
How much does it cost to bend metal around windows labor cost?

Typically, you might expect to pay anywhere from $50 to $100 per hour for skilled labor. Overall project costs can range from a few hundred to several thousand dollars, depending on the specifics of the installation. It's best to get quotes from local contractors for a more accurate estimate.
How do you repair a roll journal?
To repair a roll journal, first, clean the damaged area thoroughly to remove any contaminants. Assess the extent of the damage; if it's a minor surface issue, you may apply a specialized repair compound or epoxy designed for metal surfaces. For more severe damage, machining the surface may be necessary to restore its shape and smoothness. Finally, ensure proper alignment and lubrication before reinserting the journal into service.
Examples of effects of heat on matter?
Expansion, example the railway tracks. This is because when the metal expands on hot days, the track doesn't bends
How do I open my locked file cabinets?
Depending on your locked file cabinet type, you may be able to open the locked cabinet if you tilt it enough so that there is a hole that your finger can poke through. You should then feel a metal piece, so push the metal up, and this should release the locks. However, if you do not have that type of cabinet, you may have to contact the cabinet company for an extra set of keys, or at last resort, destroy the cabinet.

Why does a rubbed plastic object stay charged but a rubbed metal object lose its charge?
Rubbed plastic objects tend to hold onto their charge because they are insulators, meaning that they do not easily allow charge to flow. Rubbed metal objects, on the other hand, are conductors and can easily lose their charge as the electrons can move freely within the material and dissipate.
What will happen if a metal rod is rubbed together with silk?
When a metal rod is rubbed together with silk, electrons transfer from the metal rod to the silk due to the difference in their electron affinities. This creates a charge imbalance, with the metal rod acquiring a positive charge and the silk a negative charge. This is known as triboelectric charging.
