A team of New York University scientists has created a gear mechanism that relies on fluids to generate rotation. The ...

Abstract: Traditional involute gears transmission problems are discussed in this paper, optimum design of the tooth profile is elicited, and then the involute-circular arc gear is introduced. The ...

Abstract: This paper presents a modified numerical model for Elastohydrodynamic lubrication (EHL) calculations of involute spur gears. This model considers the fluid as a Newtonian fluid. The main ...

While bones can regrow themselves when they break, teeth aren’t so lucky, and that leads to millions of people worldwide suffering from some form of edentulism, a.k.a. toothlessness. Now, Japanese ...
