Knee bracing explained

Knee bracing explained. Structures tend to wobble and this is what fixes it. Let's get after it. When figuring out your knee brace for a post and beam setup, a good rule of thumb is 1/3 of the post and 1/3 of the beam. So, in our case, this overall dimensions here are 3 ft by 3 ft. So, when you're measuring for something like this, it's important to measure from the same point. Don't measure up here one way and in here the next way. Just measure from the same point. So, measure 12 down and measure the same point 12 across. Now, we got to figure out this measurement. So, to figure out this angle, we're going to do a little bit of math and that's where this comes in. We've all learned this in school. So, we have 12 in squared equals 144 plus 12 in squared, which is 144. So, 144 plus 144 equals 288. Now, the square root of 288 is 16.97. It's a 30 seconds short of 17 in. So, go ahead and cut your bracing at 17 in. When cutting your 17 in brace, you want to go outside of 45 to outside of 45. So, if we measure this here, 17. Let's screw it in. Now, look at that. Nice and rigid. That's why triangles are everywhere in construction. Whether it's shelves, pergolas, decks, or post and beam framing, triangles are everywhere. That's it for triangle Tuesday. I got stuff to do. I'll catch you guys on the next one. Peace.
