I came across a diagram of a release mechanism, which shows the operator how to double a release load. I have taking a basic physics course (not advanced) and I can't seem to make any sense of this. I am just trying to understand this diagram; is it correct? Sorry for the drawing; hopeful that it is understandable. The diagram states that the release load of a single unit can be doubled by rigging the release as shown in the diagram. My Thinking: It seems that the static load will be shared by the chain and the release unit. This does not mean that the release load of the release unit will be doubled. The release load is set by the capacity that the release unit can handle (release mechanism motor). The load is attached to the link in the middle of the chain. The top has three shackles that is attached to a stationary object. I cannot seem to wrap my head around this; can someone please give me some (physics) knowledge on how this can work or doesnt work? This seems like basic knowledge, so would like to have a refresher course with details on how this works or doesnt work. Thanks in advance.
