Bore describes the size of hole in something that has a hole as its main feature, e.g. a gun.
The parts of a Bunsen burner has collar,base.air hole and barrel. Collar : Adjust size of air hole Base: Support Bunsen Burner Air hole: Allow air to enter air hole Barrel:To ensure the flame is adjusted to a suitable position
Depends on the experimnet, if you testing a reaction of metals with carbonates for example the variables might be; the size of the metal/carbonate, the amount of metal/carbonate, the from of metal e.g. solid or liquid
A grommet is a metal lining for a hole in fabric or metal through which a cable or cord passes. It prevents the hole being made larger or torn by the friction or tension of the cable or cord. Grommets are most easily spotted on tarpaulins, where they are placed in the holes through which the tie-down ropes pass.
That's just under four inches, about the size of an adult male's palm.
to enlarge to desired size (a previously bored hole) by means of a reamer.
About 20 dollars! Hey oh!
It would get larger due to the expansion of the metal (see the related links)
When a metal plate with a circular hole is heated, the metal expands due to the increase in temperature. As a result, the size of the hole also expands slightly. This phenomenon is known as thermal expansion.
The drill bit to screw size chart for metal is a guide that matches the appropriate drill bit size to the corresponding screw size for metal materials. This chart helps ensure that the hole drilled is the right size for the screw to be securely fastened in metal surfaces.
If you want it to grip, drill a 9/64 hole. For a clearance hole, drill 7/32.
As the circular metal sheet is heated, it expands uniformly in all directions, including the hole. However, since the hole is not a separate entity but simply a void within the metal, it does not grow smaller or larger. The hole appears to change size relative to the expanding metal because of the way our eyes perceive the interaction between the sheet and the hole.
For drilling through metal with a drill, use a hole saw that is slightly larger than the diameter of the hole you need. This will help prevent the hole saw from getting stuck and make the drilling process smoother.
If no drill bit this size available, can use EDM service if metal is used
For cutting through metal pipes, it is recommended to use a hole saw that is slightly larger than the diameter of the pipe. This will allow for a clean and precise cut.
the metal particles(talking about metals) near the hole will expand towards the hole making the hole smaller, and the particles at the extreme expands outwards..
When you heat a metal all of the atoms try to get further apart including those on the inside edge of the capacity. The only way to do this is by increasing the size of the capacity. You can see this in action if you've ever got a glass stuck inside another. The best way to separate them is to heat them up in hot water so that the outer glass expands. Not sure what "with capacity inside" means. When you heat a piece of metal with a hole in it, the hole gets bigger. Imagine a sheet of metal with a circle drawn on it. Heat it up. Everything expands, Including the circle. The same is true if you actually remove the metal from inside the hole.
