A research team led by Prof. Tian-Bao Ma from the Department of Mechanical Engineering at Tsinghua University has proposed a ...

This is because, on a perfectly smooth vertical surface, the normal force at the contact interface (or point), i.e., mg cos 90 is zero, resulting in no static friction force to generate the torque ...

The film discusses an experiment conducted by Professor Fredman and Dr. Madson, which investigates the heating of a copper target when bombarded by electrons. Using a setup similar to the Millikan ...

Posted: January 10, 2025 | Last updated: March 6, 2025 In this video we would like to demonstrate our new DIY Kinetic Log Splitter Machine. This machine is fully designed and built by Gojzer too.

Electrochemical systems with increasing complexity are gaining importance in catalytic energy conversion applications. Due to the interplay between transport phenomena and chemical kinetics, ...

Portland’s new ranked-choice voting system for City Council took in hundreds of thousands of ballots that each ranked up to six candidates and spit out 12 winners.

Picture this: You crack open your high school physics textbook to a drawing of a skier teetering at the top of a jump. The diagram is supposed to teach you about topics like kinetic energy, such as ...

Led by JCO and the army's Rapid Capabilities and Critical Technologies Office (RCCTO), the experiment pitted on average 40–50 UASs at a time against nine different counter-UAS (C-UAS) solutions.

Tribological tests are adopted to estimate the kinetic friction coefficient (COF) of the material of interest according to the American Society for Testing and Materials (ASTM) standard. Typically, ...
