Today, I’ll begin design of a solar-powered pile-driver<\/a> for driven wells<\/a>. Some of the information I’ll need to collect is modeling of the impulse necessary for a pointed shaft to penetrate the hard clay layers under the soil -I’m trying to find names for it, remembering “calechia”- and if there is any other rock under that where I am wishing to drive a well, and the impulse necessary for that, if any. I’m vaguely remembering that, to the depth I’m likely to need, that the “bedrock” is “unconsolidated aggregate<\/a>” in a compressed hard clay matrix.<\/p>\n

Then, I’ll need to calculate the drop necessary for various masses to provide for that impulse upon impact, what power is necessary for the D.C. motor I’ll use in a cam & cog machinery to lift and let go the driving mass, which shall determine the wattage of photovoltaic panels I’ll need for that load.<\/p>\n

So, before I can calculate the power of the motor, I’ll need to design a lifter\/releaser that works on a cycle, because I wish to design this as simply as possible, and not use robotics, though that should be more of an achievement.<\/p>\n

With some searches, I found that the layer I must have penetrated is “caliche<\/a>” -I was close- and I also realize that I must review Mechanics of Materials<\/a>, because I’m likely to have to construct a Mohr’s Circle<\/a> when I can find a tensile yield strength<\/a> for caliche, to calculate a shear yield strength<\/a>. Enough for today: other responsibilities call out for my attention. I’ll be tracking, and showing, my work on this in a page under my home site<\/a>.<\/p>\n
