Although robotic devices are used in everything from assembly lines to medicine, engineers have a hard time accounting for the friction that occurs when those robots grip objects - particularly in wet ...

Whenever you are trying to design a micromechanical system, it is likely to include the fundamental machine parts of gears, gimbals, hinges, pistons and suspended beams that flex. Brian Borovsky, ...

Conventional car brakes are built with one thing in mind, the purpose of stopping the car. Since this purpose is essential, a great deal of time and resources were invested in the evolution of such ...

The field of economics has long modelled itself after Newtonian physics. When physicists analyse a complex problem, they usually begin with the simplest version and neglect any complicating effects, ...

It makes sense to think that reducing the friction in an engine, transmission, axle, and transfer case, will result in more power available to the wheels. While correct in theory, several industry ...

Explore the dynamics of mass tipping with springs and friction in this detailed physics analysis! This video demonstrates how forces, torque, and friction interact to influence tipping behavior, using ...
