Let's say I have something like a drawbridge that is 8' long (and 4' wide, not that it matters) and weighs 100 pounds. Let's say it is hinged at one of the 4' edges, and is otherwise flat on the ground. Suppose I grab the unhinged end and pick it up. What will the downward force as I pull it up say at 0 degrees, 30 degrees, 60 degrees, and when it is vertical (90 degrees)?
This is a real problem, but the above is a simplified version to the structure I have. It's more like a steel plate that is covering a window, and eventually a winch at the top will open and close the window with the plate.
