To solve the problem in the image, we need to determine the resultant force from the five forces $K_1, K_2, K_3, K_4, K_5$ acting on point $S$. The forces have magnitudes of 1000 kg each, and a graphical solution method is required according to the problem statement. Here’s how to approach it:

Key Information:

• Each force has a magnitude of 1000 kg (equivalent to approximately $9800 \, \text{N}$, considering the gravitational constant).
• Scale: 1 cm on the diagram equals 200 kg, or $1960 \, \text{N}$.

Steps for a Graphical Solution:

1. Draw the Forces Accurately: Using a ruler, measure each of the forces on the diagram according to the given scale. The length of each force vector in cm should be scaled by multiplying it by 200 to convert it to kg.

2. Vector Addition (Head-to-Tail Method):

   • Begin by placing the tail of the second vector at the head of the first vector.
   • Continue this process for all vectors (i.e., add $K_1$ to $K_2$, then $K_3$, etc.).
   • The resultant vector will be the one that connects the starting point of $K_1$ to the end point of the last vector added.

3. Measure the Resultant: Once the resultant vector is drawn, measure its length and use the scale (1 cm = 200 kg) to convert the length into the actual force in kg.

4. Determine the Angle of the Resultant: Using a protractor, measure the angle of the resultant vector relative to the positive x-axis (or a chosen reference direction).

Calculating the Resultant Mathematically (if needed):

• Resolve each force into its x and y components using trigonometry if the angles of the vectors are known.
  • For force $K_i$ at an angle $\theta_i$ from the horizontal axis: $K_{i_x} = K_i \cdot \cos(\theta_i)$ $K_{i_y} = K_i \cdot \sin(\theta_i)$
• Sum all the x and y components: $F_{\text{res\_x}} = \sum K_{i_x}, \quad F_{\text{res\_y}} = \sum K_{i_y}$
• The magnitude of the resultant is given by: $F_{\text{res}} = \sqrt{(F_{\text{res\_x}})^2 + (F_{\text{res\_y}})^2}$
• The direction (angle) of the resultant relative to the horizontal is: $\theta_{\text{res}} = \tan^{-1}\left(\frac{F_{\text{res\_y}}}{F_{\text{res\_x}}}\right)$

This graphical approach allows you to visualize and calculate the resultant of multiple forces in a clear and systematic way.

Here are some related questions to expand understanding:

1. How do you resolve a vector into its components?
2. What is the significance of vector direction in force analysis?
3. What are the common methods for adding multiple vectors?
4. How does changing the angle between vectors affect the resultant force?
5. How would the solution change if the forces were in three dimensions?

Tip: Always ensure that your scale and units are consistent when solving problems graphically.
