Transcribed Image Text:**Adding Vectors Using the Analytical Components Method**
To add vectors using the analytical components method, follow these steps:
1. **Resolve Each Vector into Components**:
- For each vector, determine its horizontal (x-axis) and vertical (y-axis) components.
- Use trigonometry:
- \( V_x = V \cdot \cos(\theta) \)
- \( V_y = V \cdot \sin(\theta) \)
- Here, \( V \) is the magnitude of the vector and \( \theta \) is the angle it makes with the positive x-axis.
2. **Sum the Components**:
- Add up all the x-components to get the resultant x-component (\( R_x \)).
- \( R_x = \sum V_{ix} \)
- Add up all the y-components to get the resultant y-component (\( R_y \)).
- \( R_y = \sum V_{iy} \)
3. **Determine the Resultant Vector**:
- Calculate the magnitude of the resultant vector (\( R \)) using the Pythagorean theorem:
- \( R = \sqrt{R_x^2 + R_y^2} \)
- Find the angle (\( \phi \)) of the resultant vector with respect to the x-axis:
- \( \phi = \tan^{-1}\left(\frac{R_y}{R_x}\right) \)
4. **Draw the Diagram**:
- Begin by drawing each vector and its components on a Cartesian plane.
- Illustrate the resultant vector by summing the x and y-components.
- Mark angles and components clearly for better understanding.
This method helps in comprehensively understanding vector addition by breaking vectors into manageable pieces, facilitating accurate calculation and visualization.
