well I kinda get it but it is slightly confuzing. you should explain everything as if you where teaching a 4 year old. Spell out every word (dont use the v=volts, t=torque till later) the equations should be broken down. even when you describe newtons, dont be afraid to over babyfi it. the simpler and the easier to read the better. when you get further on in the book like 10 pages at least, then start abbreviating. and also add a chart with all abbreviations you can think of. the chart would do good on the first page right after the contents. This way readers will have a chance to read it before they start the actual gear ratio and motor stuff.
for example:a=acceleration(definition)
a/c=alternating current (current found in your house outlets)
v=volts
and so on. (only use this part for abbreviations you will be using or that readers may encounter.)
and as for the breaking down of the equations put stuff like
EX: here the X indicates the cross product (small note on what cross product is) of the two vectors(Force and radius)
EX2: the length of the lever "ie:the gear" is in fact the radius of the gear. this radius = 2centimeters/2 =1cm
(and describe why the 2 cm is divided by two)
then
EX3: (keep the picture of the problem you are working with, with the equation thing. I got confuzed

when the big gear is right there, I thought we had started talking about that) and also put F=torgue/radius.
Either way it will be easier to understand for us rookies.
