### Problem Statement

Consider a beam of length \( L = 11 \) feet with a fulcrum \( x \) feet from one end as shown in the figure below. Two objects weighing 36 pounds and 96 pounds are placed at opposite ends of the beam. Find \( x \) (the distance between the fulcrum and the object weighing 36 pounds) such that the system is in equilibrium.

### Diagram Explanation

The diagram illustrates a beam balanced on a fulcrum. The beam has a total length of 11 feet. There are two objects placed at each end of the beam:
- **Object 1** (weighing 36 pounds) is placed on the left end.
- **Object 2** (weighing 96 pounds) is placed on the right end.

The fulcrum (pivot point) is located \( x \) feet from Object 1. The distance from the fulcrum to Object 2 is \( L - x \) feet.

In equilibrium conditions, the moments around the fulcrum must balance out. The moments are calculated by multiplying the weight of the object by its distance from the fulcrum.

### Multiple Choice Options

\[ \begin{aligned}
\text{9 feet} \\
\text{10 feet} \\
\text{7 feet} \\
\text{8 feet} \\
\text{6 feet}
\end{aligned} \]

### Equilibrium Condition

To solve for \( x \):
1. Use the formula for moments about the fulcrum.
2. Set the anticlockwise moments equal to the clockwise moments:
\[ 36 \cdot x = 96 \cdot (11 - x) \]

3. Solve the equation for \( x \):
\[ 36x = 96 \cdot (11 - x) \]
\[ 36x = 1056 - 96x \]
\[ 132x = 1056 \]
\[ x = \frac{1056}{132} \]
\[ x = 8 \]

So, the correct answer is:
\[ \boxed{8 \text{ feet}} \]
