Constant Velocity Joints ✔

greetings to one and all watching this video. MECH EXPLANATIONS welcomes you. let us learn about Constant-velocity joints. Constant-velocity joints (also known as homokinetic or CV joints) allow a drive shaft to transmit power through a variable angle, at constant rotational speed, without an appreciable increase in friction or play. They are mainly used in […]

Brickwork Articulation Joints

So this is articulation joints. All right. This is pretty important stuff especially, like, with cracks, I mean one of the bigger things that we always seem to do is quote underpinning and you know a lot of the time it’s not, you know, because of underpinning we want to make sure that the joints […]

Cross Cut Sled w/ Finger Joint Jig Insert

Man these old jigs take up a lot of space! Grrr, warped and unusable! Let’s make a new one. Some scrap plywood (from failed attempts at kerf bending) Cleaning up the edges. Some scrap 2×4’s Jointing the faces smooth. Squaring up the ends Routing a chamfer. This will let dust collect there and not affect […]

NASA Now Minute: Engineering: Friction Stir Welding

[ Sound Effects ] The science behind welding for space. [ Sound Effects ] Generally speaking, there are two types of welding. There’s fusion welding and solid-state welding. Some of the fusion processes, we’re more familiar with, you know, that’s the stick electrode or the gas metal arc welding. The solid-state welding is a bit […]

Electric Circuits Part 5 – Effects of the Electric Current , the Fuse

Hi and welcome to part 5 of the introduction to Electric Circuits! In this part: Main effects of the electric current. The three main effects of an electric current are: magnetic, chemical and heating effect. Some of the most common practical applications of the effects of an electric current include: relays, bells, motors, generators and […]

Analysis of Merge sort algorithm

In our previous lesson, we had explained merge sort algorithm. Now, in this lesson we are going to analyze merge sort algorithm. We will look at various properties of merge sort algorithm. We will try to see how efficient it is terms of time and space complexity. Some of the properties of merge sort algorithm […]

Wake: UNC Asheville students combine art and engineering.

Hello, my name is Mel Chin. I’m working here with students from the University of North Carolina at Asheville in the STEAM Studio to create a major installation for Times Square. The work will be called “Wake.” “Wake” is more of a sculptural commentary from the past about human relationships to climate, and it will […]

Crab Shells and Trees Combine to Create New Food Packaging

– Approximately, one-third of the food that comes from farms for example, gets wasted before it gets to a consumer’s table. One of the ways that this problem is going to be solved as the population of the planet grows is using packaging. What our research is trying to do is to create sustainable solutions […]
