![### Understanding the Center of Gravity in a Barbell System
This section will help you compute the center of gravity for a simple barbell system presented in the illustration.
#### Problem Statement:
Compute the center of gravity of the barbell system drawn in Figure 5.10. Assume that the weight of the 36-inch connecting rod is negligible.
#### Diagram Explanation:
- The diagram shows a horizontal bar with weights at both ends, similar to a barbell.
- There are two weights:
- A 30 lb weight on the left.
- A 10 lb weight on the right.
- A central point labeled "C.G." (Center of Gravity) is marked on the bar.
- The total length of the barbell is 36 inches.
- The force of gravity is acting downward on both weights.
### Calculation Process:
To determine the center of gravity (C.G.) of this barbell system, consider the balance of moments about any point, typically set at the center.
The formula used to calculate the position x of the center of gravity is:
\[
x = \frac{\sum (w_i \times d_i)}{\sum w_i}
\]
Where:
- \( w_i \) are the weights.
- \( d_i \) are the distances from the point of reference, usually one end of the rod.
Here, the reference point is usually one weight or the center of the rod.
Let's assume the left weight (30 lb) is at position 0, and the right weight (10 lb) is at position 36 inches from the left. Using the balance of moments, you can solve for x to find the center of gravity's position on the bar.
This approach helps in applications where knowing the center of gravity is crucial for stability and balance, such as in engineering and physical design.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fb1d35e75-0020-4867-ac6c-a56d05dfee21%2Fbd34f054-8033-4475-849d-33d0f3278e82%2Ffw6cs1n_processed.jpeg&w=3840&q=75)
