This week I started working with the design of my piston again and drew up some more variables for when I actually start measuring the dimensions of the parts. The drawing uses both, the variables that I used in last weeks diagram with added new ones, so, for this reason, I am re-uploading the picture from last week so that it will be easier to refer to both at the same time.
The dimensions from last weeks picture used in this diagram are x and z, where x is the length of the individual segments of the piston, and z is the number of segments in the piston. These are used in combination with a new variable r, which is the radius of the first segment, and q, which is the distance between segments, to find the radius of the last segment. As seen in the diagram, when moving to the next segment, the radius is reduced by two times that of q, the distance between segments. Therefore the radius of the last segment is the radius of the first with two times q times the number of segments, z, minus 1.
