Which of the following materials requires highest shrinkage allowance?...
Shrinkage allowance is the difference in dimensions between the pattern and the final casting due to the shrinkage of the metal during solidification. The amount of shrinkage allowance required is dependent on the material being used for casting.
Explanation:
Steel has the highest shrinkage allowance among the given materials. This is due to the following reasons:
1. High melting point: Steel has a high melting point compared to other materials. This means that it takes longer for the metal to cool and solidify, resulting in more shrinkage.
2. High carbon content: Steel has a higher carbon content than other materials. Carbon is a strong carbide former, which can lead to a reduction in the solidification range of steel, resulting in more shrinkage.
3. Low thermal conductivity: Steel has a lower thermal conductivity than other materials. This means that heat is retained for a longer time, resulting in a longer solidification time and more shrinkage.
4. High density: Steel has a higher density than other materials. This means that it will shrink more during solidification.
Therefore, steel requires the highest shrinkage allowance among the given materials.

Which of the following materials requires highest shrinkage allowance?...
I think brass is correct answer because for brass 23mm per m length
where as fir steel its value is 20 mm per merer length
where as fir steel its value is 20 mm per merer length
