In oil-shear brake and clutch units, friction plates and oil work together to slow and accelerate systems. Consider oil-shear clutching: Upon startup, rotating input discs move toward stationary ...
In November 2008, the space shuttle Endeavor visited the International Space Station to do some important repair work. A critical part of the mission was to service the station’s two rotary joints, ...
Chemists and engineers have discovered a fundamental friction law that is leading to a deeper understanding of energy dissipation in friction and the design of two-dimensional materials capable of ...
