  • PHYSICS PROJECT REPORT ON BALL BEARING

    Ball and roller bearings, generically called rolling bearings, are commonly used machine elements. They are employed to permit rotary motions of, or about, shafts in simple commercial devices such as bicycles, roller skates, and electric motors. They are also used in complex engineering mechanisms

    2019-11-29 · An intriguing question arises as to whether C60 molecules can act as “molecular ball bearings,” that is, preventing direct contact between two solid surfaces while simultaneously dissipating shear stress through fast rotation. To explore this, we performed measurements of friction across a solution of C60 in the boundary lubrication regime.
