**Telescoping Arm ABC Overview:** The telescoping arm labeled ABC is used to provide an elevated platform for construction workers. In this scenario, the workers and the platform have a combined mass of 212 kg. The center of gravity for this combined mass is situated directly above point C. The angle θ is given as 20°. **Diagram Explanation:** - **Arm ABC:** - The arm is divided into three segments: - From A to B, measuring 2.4 meters. - From B to C, measuring 5 meters. - **Position and Angles:** - The angle θ at point B is 20°. - **Platform and Workers:** - Positioned at point C on the arm. - **Support and Base:** - The distance from the base of the support structure (D) to the ground is 0.9 meters. - The horizontal distance from the base D to the point directly below A is 0.5 meters. **Task:** - Draw the free-body diagram of the arm ABC to illustrate the forces acting on the system, including gravitational forces and any relevant reaction forces or torques.
