It’s official: [Engineer Bo] wins the internet with a video titled “Finding NEMA 17,” wherein he builds a dynamometer to find the best stepper motor in the popular NEMA 17 frame size. Like a lot of subjective questions, the only correct answer to which stepper is best is, “It dep...
But it runs, and in the end, that’s really the most important thing with a project like this. Improvements will come with time, especially once [Leo] finishes building the dynamometer he hopes will give him some solid data on how the engine’s overall performance is impacted as he makes...
such as limited mobility, limited independent access to outside facilities/activities and lack of social interaction, present barriers to maintaining physical activity (PA) levels [7]. PA has been shown to have significant positive effects on the healthy ageing trajectories of older adults [8], wi...
…I didn’t want any of our investors (or the company) to look lame, which I thought was the inevitable outcome if I expressed the facts of what happened we weren’t actually directly solving the energy storage problem — we didn’t want or need the press to solve it, but… …I did...
moteus has a variety of testing done on every firmware release. There are unit tests that run with pieces of the firmware compiled torun in a host environment. There is a hardware-in-the-loopdynamometer test fixturethat is used torun a separate battery of tests. There is also anend-of-lin...
Testing your grip strength before a workout could save you an unnecessary trip to the gym. Your grip force is an excellent indicator of the condition of the rest of your body. You can test your grip strength with a cheap, readily available hand grip dynamometer. Take readings every day for...
Using a dynamometer car coupled to the original six car consist the the train achieved a top speed of 112.5 mph and averaged 74.9 mph during trials held on May 15th while in regular service it averaged 80-81 mph. For all of the Hiawatha's beauty much of its legend comes from its speed...
Emissions are measured in the lab using a chassis dynamometer on test cycles such as the FTP-75 (Federal Test Procedure). Download: Download high-res image (128KB) Download: Download full-size image Fig. 2. US tailpipe emissions standards. Europe has also set increasingly stringent criteria ...
and added a flex point in the center of the body. Two linear actuators work together to make the vehicle bend, and therefore give it the ability to steer and turn. A normal tread would be unable to bend in this way, but the twist in the Möbius tread accommodates this pivot point ...
Grip strength was measured with the hydraulic hand dynamometer JAMAR (Sammons Preston, Chicago)31. The participants were seated with their arm in 90° of elbow flexion (antigravitational support was provided for the elbow position when needed by the tester) and instructed to squeeze the dynamometer...
