While making a wooden wheel, the iron rim is made slightly smaller tha...
Explanation:
Reason for making the iron rim slightly smaller:
The iron rim is made slightly smaller than the wooden wheel because of the difference in the expansion and contraction properties of iron and wood. Iron expands and contracts more than wood when heated or cooled.
Process of fitting the wooden wheel into the iron rim:
1. Heating the rim: The iron rim is heated, causing it to expand. This expansion creates a larger opening in the rim.
2. Putting the wooden wheel in the expanded state: The wooden wheel is then put into the rim while it is still in its expanded state. The larger opening in the rim allows the wooden wheel to fit inside easily.
3. Cooling and contraction: After the wooden wheel is placed inside the rim, both the rim and the wheel are allowed to cool. As the iron rim cools, it contracts and becomes smaller in size.
4. Tight fit: The contraction of the iron rim creates a tight fit between the rim and the wooden wheel. The rim contracts more than the wooden wheel, causing it to grip the wooden wheel firmly.
Reason for choosing option 'A':
Option 'A' is the correct answer because it accurately describes the process of fitting the wooden wheel into the iron rim. It explains that the iron rim is made slightly smaller than the wooden wheel to account for the expansion and contraction of the materials. When the rim is heated and expands, the wooden wheel is placed inside. As the rim cools and contracts, it tightly fits the wooden wheel.
Other options and their explanations:
- Option 'B': This option states that the iron expands on cooling, which is incorrect. Iron expands on heating and contracts on cooling.
- Option 'C': This option states that the wooden wheel contracts on heating, which is incorrect. Wood generally expands on heating and contracts on cooling.
- Option 'D': This option includes all the incorrect explanations mentioned in options 'B' and 'C'.
Therefore, option 'A' is the correct answer as it provides an accurate explanation of why the iron rim is made slightly smaller than the wooden wheel.

While making a wooden wheel, the iron rim is made slightly smaller tha...
Explanation:
Reasoning:
The reason why the iron rim is made slightly smaller than the wooden wheel is due to the difference in the thermal expansion properties of iron and wood. When heated or cooled, different materials expand or contract at different rates. In this case, iron and wood have different rates of expansion and contraction.
Here's a detailed explanation of why option A is correct:
1. Thermal expansion: When heated, most materials expand, including iron. This is due to the increase in the kinetic energy of the atoms or molecules, causing them to vibrate more and occupy more space.
2. Wooden wheel: The wooden wheel is not affected much by temperature changes compared to iron. Wood has a relatively lower coefficient of thermal expansion compared to metals like iron.
3. Smaller iron rim: By making the iron rim slightly smaller than the wooden wheel, it allows for the expansion of the rim when heated.
4. Assembly process: The wooden wheel is first heated or soaked in water to make it expand slightly. This expanded wooden wheel is then fitted inside the iron rim.
5. Cooling: As the assembly cools down, the iron rim contracts due to the decrease in temperature. The contraction of the iron rim results in a tight fit with the wooden wheel.
By following this process, the wooden wheel and iron rim are effectively joined together, creating a sturdy and durable wooden wheel with an iron rim.
Conclusion:
The option A is correct because the iron rim is made smaller than the wooden wheel to account for the expansion of iron when heated. This allows for a tight fit between the iron rim and the wooden wheel when the assembly cools down.
The correct option is A: Because on heating the rim, the iron expands. The wooden wheel is then put in the rim in its expanded state. On cooling, the iron rim contracts and fits tightly with the wooden wheel.
