Answer

To solve the question "Static friction is always _____ and _____ to the applied force," we need to analyze the characteristics of static friction.

### Step-by-Step Solution:

1. **Understanding Static Friction**:
- Static friction is the force that prevents an object from moving when a force is applied to it. It acts on objects that are at rest.

2. **Analyzing the Forces**:
- When a force (let's call it F) is applied to a stationary object, static friction acts in the opposite direction to counteract this applied force.

3. **Magnitude of Static Friction**:
- The magnitude of static friction adjusts itself to be equal to the applied force until it reaches a maximum value. This means that if the applied force is F, the static friction force will also be F, but in the opposite direction.

4. **Direction of Static Friction**:
- Since static friction acts in the opposite direction to the applied force, it is always opposite to the direction of the applied force.

5. **Conclusion**:
- Therefore, we can conclude that static friction is always **equal** and **opposite** to the applied force.

### Final Answer:
Static friction is always **equal** and **opposite** to the applied force.
