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 36 – A summary of a right triangle and trigonometry.

When I started this web site my goal is to talk about the things I like and instruct others to do the same. The goal is for the most part to not present plans and step-by-step instructions, but more to present ways to reason through problems and come up with solutions. Technique and knowledge is

Episode 35 – A circle, angles, and a triangle.

pi top

In this post we switch gears again and present some math to help us calculate and understand some things.

It will be helpful to review Episode 17 Triangle & Complementary Angles and Episode 24 Ratio and Proportion and Right Triangles before listening to this episode..

First I define a special type of circle. The radius

Episode 31 – Cutting and Sawing part 1

Close up of the carbide tips on a Circular Saw Blade

This is the first of probably three episodes talking about cutting and sawing. The main topics are saw set, and the number of teeth per inch on saw blades and the width of the saw cut, or saw kerf created by the saw blade.

Binding of the saw blade is discussed and the reason for

Episode 27 – Statics Part II – Moments

A drawing of the problem to be solved

First, I want to announce the Repurpose Contest page is up. This includes pictures of the items for the April 2012 contest.

This episode is the next step in complexity from Episode 25. The problem is very similar to the last one except the force and the rope are connected at different points.

A

Episode 25 – Introduction to Statics and Forces on a Beam

This episode baby-steps into understanding how to solve problems to determine the forces on structural members. A completely graphical method is used to solve this problem by drawing right triangles and measuring the line lengths. A simple experiment is shown to roughly test the results. I show how I did the experiment, but I recommend

Episode 24 – Ratio and Proportion and Right Triangles

In this episode I talk about a right triangle again and present the concept of scaling. I also talk about an important safety subject on some youtube videos I watched last night.

The first picture shows the naming of the sides and angles in a right triangle. The three angles in any triangle must add

Episode 5 — Making Things Square

In this episode we talk about three important uses of the word square. Then we drill down into the term square as used by craftsmen and builders. We then talk about square from a geometry point of view and describe the meaning of a parallelogram, a rectangle and a square.

Next we drive home the

episode 3 – A Line

In this episode we discuss a line.

The definition of a line is the shortest distance between two points.

Adding a 3rd, or 4th or…. point(s) on that line between the two outer points is called interpolation. We will discuss two practical methods of doing that using our eye or a string.

Extending a line

Episode 2 Measurements

It this post I talk about measurements.

The first question is how accurate do you need to be. You have to determine that because absolute accuracy is not always necessary.

After that I discuss things that decrease accuracy. Most of the time inaccuracy is due to technique and not a problem with the tool.

When
