In this study, with the aim of improving fatigue characteristics A7075 aluminum alloy, A7075-T6511 alloy rod specimens were plated electroless Ni–P different compositions, and evaluated by a rotary bending test. The strength specimen low-P type was higher than that un-plated specimen. However, high-P significantly lower specimen, medium-P also though extent not so significant. It speculated the...

Gearing is one of the most effective methods for transmitting power and rotary motion from the source to its application with or without change of speed or direction. The bending and surface strength of the gear tooth are considered to be one of the main contributors for the failure of the gear in a gear set. Thus, determination of stresses has become popular as an area of research on gears to ...

The proton-driven ATP synthase (FOF1) is comprised of two rotary, stepping motors (FO and F1) coupled by an elastic power transmission. The elastic compliance resides in the rotor module that includes the membrane-embedded FO c-ring. Proton transport by FO is firmly coupled to the rotation of the c-ring relative to other FO subunits (ab2). It drives ATP synthesis. We used a computational method...
