"Descending devices" (e.g., ATCs, Brake Bar Racks, Figure 8s, Rescue 8s, etc) create friction as their primary purpose. The friction in descending devices is always considered when calculating forces.
The "Safety Factor" is the ratio between the gear's breaking strength and the maximum load applied to the gear (e.g., 5:1).

: Create the writer object by specifying the output name, codec, frames per second (FPS), and frame size. out = cv2.VideoWriter('vid_522_output.mp4', fourcc, 20.0, (640, 480)) .
: Ensure the FPS argument is passed as a float to avoid initialization errors on some platforms. About the MP4 Format
