While thinking about bell cranks and how they function, I realized that a simple rope and pulley arrangement could achieve the same result in many cases.
Thanks XRay. I usually strive for minimalist designs, but hadn't thought of that. It would be hard to get something simpler than a rope and pulley for transferring a tensile force in another direction accurately and with unlimited travel.
BUT..... You cannot push a rope! So, a rope and pulley will only work the same as a bell crank as long as you only need to pull, and not push. Of course, if you need to push, then you would need a rigid rod on both the input and the output of the bell crank. (I'm still thinking! lol)
