Transcript text: Heating a bearing increases the size of the bearing, allowing it to slip over a shaft.

Solution

Solution Steps

Step 1: Understanding Thermal Expansion

When a bearing is heated, it undergoes thermal expansion. This means that the material of the bearing expands as the temperature increases. The expansion allows the bearing to increase in size, which can make it easier to fit over a shaft.

Step 2: Application of Thermal Expansion

In practical applications, heating a bearing is a common technique used to facilitate the assembly of mechanical components. By increasing the temperature of the bearing, it expands slightly, which can help it to slip over a shaft without the need for excessive force.

Step 3: Conclusion

The principle of thermal expansion is utilized to increase the size of the bearing temporarily, allowing it to fit over a shaft more easily. This method is efficient and helps in the assembly process of mechanical systems.
