The 'spin-transfer torque effect' could provide a powerful means of controlling the orientation of spins with electric currents rather than magnetic fields in future spintronic devices. Quantitative ...

Everyone loves perpetual motion machines. They are a representation of the highest level of creativity in finding loopholes in the laws of physics. Let's take a look at this one. What is a perpetual ...

Twisted light: self-torque could be used to manipulate molecules. (Courtesy: iStock/VikaSuh) Physicists in Spain and the US have shown that the orbital angular momentum, or twistedness, of light can ...

Quasiparticles with linear dispersion in condensed matter 1 systems have sparked considerable excitement since their discovery in graphene 2, topological insulators 3, Dirac semimetals such as Na 3 Bi ...

Unlock the mysteries of rolling motion, torque, and angular momentum in Chapter 11! Learn how rotational motion works and how it differs from linear motion. #RollingMotion #Torque #AngularMomentum #Ph ...

Suppose you have a cylinder on an ramp and you let it start rolling down. What will be its acceleration? Great question, right? I like this because it brings in many different concepts in introductory ...

Most people think tightening wheels after fixing a flat tire is simple — grab a wrench, lean on it until your shoulder pops (ouch!), and call it a day. But wheel torque isn't just about brute force -– ...

We may receive a commission on purchases made from links. It may look like a fancy ratchet, but a torque wrench's more elaborate mechanism adds a crucial feature: measurement. It replaces the ...

Editor’s Note, 10/31/25: For this latest update, we added three new tools. The Craftsman 1/2-Inch Drive Torque Wrench is long and ideal for torquing larger bolts and fasteners. The Precision ...
