storm-lightning-bolt-md

In this episode I talk about the definitions of energy, work, an power. This episode was created because I found that I needed to lay a foundation before I talked about insulation and the conservation of energy. We often use the words power and energy interchangeably and that is incorrect. Energy is the ability to

Episode 44: Programming to learn logical thinking.

In this episode I discuss an easy and inexpensive way to learn programming. Python is my language of choice for this because it is Open Source Software that is freely distributed and has excellent documentation to walk you through programming. It is also very powerful software and it works on Linux, Windows, and Mac’s.

Programming

Episode 43 – Angles – A simple problem and a not so simple one

boardcut

In this episode I discuss the simple problem of making boards or pipes butt up to each other correctly for angles other than 90 degrees. Later I discuss the complete calculations for the real-life problem of my grape arbors discussed in the last episode. That is not a simple set of calculations.

The key to

Episode 42 – An Angle Mistake

I worked on a home project and I goofed up. Oh well, my goof-up is an opportunity for you to learn. I guess this is an excellent case of do as I say not as I do. Seriously, this is not going to be a big problem for me, but at other places it could

Episode 41 – Framing a building

pix1_epi041

In this episode I am going to show how we built the frame of a building. The main purpose of this is to show how wood is “stacked” so the position of the wood uses the strength of the wood while the nails are mostly nothing more than pins keeping the wood from moving.

This

Wood is a universal construction material, and needs to be understood if it is used to construct almost anything. In this episode we discuss how wood grows and how it really is a composite material made up of fibers held together with a type of glue.

As the wood grows it’s growth rate is not

Episode 38 – Popsicle sticks and Bicycle frames.

In this episode we discuss why beams (and Popsicle sticks) bend and why bicycle frames are hollow. This is an easy and quick no-math episode that presents the forces determining the strength and rigidity of beams.

In episode 12 we talked about bending forces on beams and I used a popsicle stick as an example.
