Hello lemgineers!...
I had an idea a little while ago that tunnel boring machines should just keep going. Think of all the tunnel we could have if all the TBMs just never stopped. We could have an ever growing tunnel network that could be tapped into as needed.
Is there any mechanical engineers? What you would wish to know when you were starting learning? What skills and topics you consider the most useful in mechanical engineering?...

I just started getting interested in synchronous machines, and this channel really did it for me. Great for anyone studying engineering, or anyone interested with a high school/first year university physics background.
We determined that the probable cause of the collapse of the Fern Hollow Bridge in Pittsburgh, Pennsylvania, was the failure of the transverse tie plate on the southwest leg of the bridge, a fracture-critical member (nonredundant steel tension member), due to corrosion and section loss resulting from the City of...

I’m thinking of just adding a potentiometer to a car headlight kit, this serves two purposes, 1. Allows me to have bright ass lights in place of my shitty Prius lights on long country roads while letting me turn down the brightness to not blind people in front of me. And 2: I think this would be a fun project to learn a little...

Under structural-only DP loading, a certain amount of deflection is allowed, and a certain amount of post-loading set displacement (permanent deformation) is allowed. Under the DP (design pressure) system, DP ratings are defined differently for structural, water leakage, and air leakage tests. This is a structural only test, so...
Earlier today, Scottish adventurers Chris and Julie Ramsey were finally able to announce their completion of the nine-month, 17,000-mile “Pole To Pole EV” expedition, the world’s first drive from the 1823 Magnetic North Pole to South Pole....

This quick video by Steve Mould has a neat visualization of metal grain structure.
A friend recently pointed out that, despite most microwave ovens having a Popcorn function, most bags of popcorn specifically say NOT to use that function. It got me wondering how the Popcorn button works (or doesn’t work). Apparently there are several different approaches in common use....
This video has some fantastic demonstrations of how sewing machines work. If you’re mechanically inclined then it’s definitely worth a watch. The mechanisms that grab, twist, and pull the thread are wonderfully clever and elegant.
This display shows stages of forming a German World War I helmet, from a flat blank to finished product....
