Think of a rocking chair and a container whose contents I don't want to settle. Easy, just place it on my lap and rock backwards and forwards. It would get a bit tedious after a while so I need to dream up some sort of mechanism to do this for me. Thought of using a cam but the trig feels like a simultaneous equation might be involved.
The shape of the cam is a circle segment that when moved along the horizontal will tilt the angle of the chord to the horizontal. Only two things are known: the length of the chord some 400mm and the maximum tilt angle of 7 degrees. In order to construct the cam I need the radius associated with the arc. Would very much welcome some guidance on how the radius might be obtained. Thx.
