The basic static capacity of a ball bearing depends on the number of balls in a row and the square of the diameter of the ball. Here's a detailed explanation of why option 'C' is the correct answer:
1. Introduction to ball bearings:
- A ball bearing is a type of rolling element bearing that uses balls to separate the moving parts of a bearing.
- It reduces rotational friction and supports radial and axial loads.
2. Basic static capacity of a ball bearing:
- The basic static capacity of a ball bearing refers to its ability to withstand a static load without excessive deformation or failure.
- It is an important parameter to consider when designing or selecting a ball bearing.
3. Factors affecting the basic static capacity:
a) Number of balls in a row:
- The more balls there are in a row, the greater the load-carrying capacity of the ball bearing.
- This is because the load is distributed among a larger number of balls, reducing the stress on each ball.
b) Square of the diameter of the ball:
- The square of the diameter of the ball directly influences the contact area between the balls and the raceways.
- A larger contact area allows for a higher load-carrying capacity.
- Additionally, a larger ball diameter also provides more surface area for load distribution.
4. Explanation of option 'C':
- Option 'C' states that the basic static capacity is directly proportional to the number of balls in a row and the square of the diameter of the ball.
- This means that increasing either the number of balls or the ball diameter will result in an increase in the basic static capacity of the ball bearing.
- The square relationship indicates that any increase in these factors will have a squared effect on the load-carrying capacity.
5. Comparison with other options:
a) Option 'A': The number of balls in a row and the diameter of the ball are directly proportional to the basic static capacity, but there is no square relationship mentioned.
b) Option 'B': The square of the ball diameter and the inverse of the number of rows are mentioned, but there is no mention of the number of balls in a row.
d) Option 'D': The inverse relationship between the square of the ball diameter and the basic static capacity contradicts the understanding that a larger ball diameter increases the load-carrying capacity.
In conclusion, the basic static capacity of a ball bearing depends on the number of balls in a row and the square of the diameter of the ball. These factors directly influence the load-carrying capacity of the bearing and are crucial in its design and selection.

In conclusion, the basic static capacity of a ball bearing depends on the number of balls in a row and the square of the diameter of the ball. These factors directly influence the load-carrying capacity of the bearing and are crucial in its design and selection.
