# Temperature Required for Brass Plug and Iron Ring to Fit

• Jayhawk1
In summary, the problem is about finding the common temperature at which a brass plug with a diameter of 8.755 cm and an iron ring with a diameter of 8.745 cm can fit together. The coefficients of linear expansion for brass and iron are given as 10x10-6(Co)-1 and 12x10-6(Co)-1 respectively. Further assistance is needed to solve this problem.

A brass plug is to be placed in a ring made of iron. At room temperature (20oC), the diameter of the plug is 8.755 cm and that of the inside of the ring is 8.745 cm. They must be brought to what common temperature (in Co) in order to fit? The coefficient of linear expansion for brass is 10x10-6(Co)-1 and that for iron is 12x10-6(Co)-1.

I don't know what to do with this... I know I have to subtract and divide some of these numbers, but I have no clue as to how to do it exactly. I need help please! Thank you.,

I still am confused...

I need more help please.

## 1. What is the ideal temperature for a brass plug and iron ring to fit together?

The ideal temperature for a brass plug and iron ring to fit together is around 425-475 degrees Fahrenheit. This temperature allows for the metal to expand and contract, allowing for a tighter fit.

## 2. Can the temperature affect the fit of the brass plug and iron ring?

Yes, the temperature does affect the fit of the brass plug and iron ring. As mentioned before, when the metal is heated, it expands, and when it cools, it contracts. This expansion and contraction can affect the fit of the brass plug and iron ring, so it's important to use the correct temperature for a proper fit.

## 3. Is there a specific heating or cooling method that should be used?

There are a few different methods that can be used to heat or cool the brass plug and iron ring. Some common methods include using a furnace, a torch, or a cold water bath. It is important to follow the manufacturer's instructions and use caution when handling heated metal.

## 4. How long should the brass plug and iron ring be heated or cooled for?

The length of time needed to heat or cool the brass plug and iron ring will depend on the size and thickness of the metal, as well as the method being used. It is best to refer to the manufacturer's instructions for specific heating or cooling times.

## 5. Is it necessary to use a specific type of brass and iron for this process?

Yes, it is important to use the recommended type of brass and iron for this process. Different types of metals have different melting points and expansion rates, so using the correct materials will ensure a proper fit. It is also important to ensure that the brass plug and iron ring are made of the same type of metal.
