Apologies in advance if this seem inappropriate as it is not my intention to offend, but after searching for some time on the use of basic levers I have still not solved what is probably the most simplest of questions to the mechanically educated - and well.. this is a mechanical design forum so I am sure this is the place to find answers. I would like to build a device which transfers a small amount of horizontal movement into vertical movement (the transferred vertical movement is greater than the horizontal movement - from a distance perspective). **Warning: Do not click on the link below if you are easily offended** A picture tells a thousand words so here is a link of what I am trying to achieve. http://www.monkeyrocker.com/function.html While the link is not particularly graphic in nature, the more sensitive my take offence so please do not click if you have a more reserved nature. Again, it is not my intention to offend, I would just like some advice on the actual mechanics involved and how such movement could be reproduced. Thanks in advance.
