Never
No. If you leave some copper wire in a square box it will never come out in a square shape.
Copper is a simple metal. It is held togeth by metallic bonds. In this setup, positively charged copper ions sit in a mutually shared "pool" of electrons. The ions are essentially held together by their attraction to these electrons. Since these electrons are free to move throughout the metal, the copper is not limited to any rigid form. Copper sulfate is a salt, consisting of positively charged copper ions and negatively charged sulfate ions. This forms a definite crystal lattice, with the ions arranged into a rigid, repeating structure. When you apply enough force to the crystal, you will force the positive and negative ions out of alignment along a portion of the structure. When this happens the bonds between the ions, which depended on this alignment, break and the crystal fractures or cleaves.
When gas is added to a rigid container using a pump, the pressure inside the container will increase due to the increase in the number of gas molecules colliding with the container walls. The temperature inside the container may also increase slightly due to the compression of the gas. The volume of the gas in the container will remain constant since the container is rigid and unable to expand.
Diamond is the allotrope of carbon that has a three-dimensional rigid structure. Its strong covalent bonds between carbon atoms form a rigid, tetrahedral structure, making diamond extremely hard and durable.
There are two: the c double bonded to o parts and the ring structure.
The rigid member in compression is typically referred to as a column. It is a structural element that primarily resists axial compressive loads.
Water
Clean the end of the pipe and the fitting where the two will connect with steel wool or sandpaper or the brush made to do it. Put a thin film on both surface's that will be touching. 1/2 to 3/4 of an inch on the end of the pipe. It help to have the flux past the area the fitting covers. Makes the solder flow easier.
Copper tube is a favorite choice for plumbing, heating, cooling and other systems. Copper tube is most often used for supply of hot and cold tap water as refrigerant line in HVAC systems. There are two basic types of copper tube, soft copper and rigid copper. Copper tubing is joined using flare connection, compression connection, or solder. Copper offers a high level of corrosion resistance, but is becoming very costly. alliedallcityinc.com
A rigid channel in hydraulics refers to a component through which hydraulic fluid flows that is in no way flexible. A steel hydraulic fitting is an example.
A necklet is a fairly close-fitting and typically rigid ornament worn around the neck.
A rigid member in compression is a structural element that is designed to carry loads primarily in compression without significant deformation. These members are typically made from materials like steel or concrete and are used in buildings, bridges, and other structures to resist compressive forces. The design of rigid members in compression involves considerations such as buckling, stability, and strength to ensure they can support the intended loads safely.
No. If you leave some copper wire in a square box it will never come out in a square shape.
If the copper is big enough, you can treat it as if it were cast and use packing and sealant. If the diameters are too different, you can use a rubber coupling to connect the two.
Rigid makes an electric soldering tool for soldering when an open flame is impractical like working in a hospital where there is flammable gases or Oxygen present.A regular type soldering iron may not get the fittings hot enough to allow for capillary attraction to draw the alloy into the fitting
Mostly used for plumbing inside a house. -Personally, I prefer PEX, easier to install and lasts longer.
