The image depicts a utility pole setup, typically used for supporting electrical or communication cables. **Diagram Description:** - **Utility Pole:** The vertical structure shown is a wooden utility pole. - **Labels:** - **Point A:** The top of the pole where the cross arms are attached. The cross arms are equipped with insulators and cables. - **Point B:** A point on the pole marked for connection with a guy-wire. - **Point C:** The base of the pole where it meets the ground. - **Point D:** A point on the ground where the guy-wire is anchored. **Measurements:** - The vertical distance from Point C (ground) to Point B is 7 meters. - The horizontal distance from the base of the pole (Point C) to the anchor point on the ground (Point D) is 2.4 meters. **Guy-Wire:** - A diagonal support cable is shown extending from Point B on the pole to Point D on the ground, used for stabilizing the pole. The setup is common in utility engineering to maintain pole stability against environmental forces such as wind or the weight of the cables.
