#Breaking-Taps #video about #MEMS accelerometers. He uses a lot of electron #microscopy to show the #flexures and other #mechanisms, then makes macroscopic replicas with #3D-printing. I don’t understand the whole flexure layout, but I appreciate the effort. He says the “gyros” use the Coriolis force generated from resonant vibration, which changes their resonant frequency. I don’t know. #toread

#video from two weeks ago on Western tank #weaponry in #Ukraine, such as the Kampfpanzer Leopard 1 with its 70mm RHA and rifled 105mm gun; the US$6 million, 70-tonne Leopard 2 with its smoothbore 120mm gun and composite armor, and at least 130 deployed to Ukraine, at least 32 damaged or lost so far (8 of these being repaired); the Stridsvagn 122+, a Leopard 2, with 10 deployed and 7 lost; Britain’s 70-tonne Challenger 2, with its 120mm rifled gun, 14 deployed and one lost so far, the first Challenger 2 lost to enemy fire anywhere in the world (the comments say a second one has just been lost in the Kursk offensive); and the 66.8-tonne turbine-powered M1 Abrams, with its 120mm smoothbore gun, 31 deployed, 10 lost. Ukraine has lost 857 tanks so far: 585 destroyed, 72 damaged, 66 abandoned, 134 captured. Their T-64 tanks were more useful for minefields because they had mine rolles, unlike the Western tanks. They say the Polish PT-91 Twardy, an upgraded T-72, has been the most useful. But somehow the video also says that the Western tanks are intimidating, advanced, and scare Russian soldiers with just the sound of their engines, even though it sounds like it’s the T-64s and T-72s that have been most useful. “#Drones are actually the reason many military experts believe tanks have been made obsolete in modern warfare, at least until the technology and tactics catch up,” and Russian drones took out at least five of the 10 Abrams tanks Ukraine has lost, prompting to remove them from the front lines. #politics
