If the spheres are of identical material, then γ12 = 0.
It is an equilibrium theory, it is only valid for short range surface forces and compliant materials (Tabor parameter greater than unity [7]), and provides no guidance on attractive forces prior to contact.
The rubber material was dicumyl peroxide cured synthetic polyisoprene.
The JKR equation that emerged from the work has found use for the interpretation of adhesion results for a wide range of materials and nanotechnological setups.

The transfer process was done so that all the structure properties, such as geometry, materials, assigned loads, frame and shell sections, and joint constraints, remained the same.
The structural members, such as columns, beams, and conventional braces, are made of steel material of grade Q345, with a nominal yield strength, fyk, of 345 MPa.
The yield deformation was calculated based on elastic modulus of steel, Es, and the yield force, which was computed using the material nominal yield strength, fyk = 235 MPa.

Introduction
Currently, the market demand for using natural products is increasing, in which extracts and compounds with natural materials for beauty are also paid more attention.
And the research works related to the development of personal care products from the source of coconut oil in the locality of Ben Tre province are still limited in the results published in prestigious domestic and national scientific journals.
Thus, with the potential of coconut oil sources available at Ben Tre, this research has been active in the source of raw materials to produce natural cosmetic products from coconut oil through the saponification of coconut oil.
Material and Methods Raw materials and chemicals.
Acknowledgements This study was supported by Ben Tre Department of Science and Technology, Ben Tre Province, Vietnam under the grant number 1136/HĐ-SKHCN.

As the battery discharges, the acid of the electrolyte reacts with the materials of the plates, changing their surface to lead sulfate.
Selecting and finding the materials for the support, shaft, gear and rack and pinion for the EPS mechanical part was a very critical job.
For this test project, the waste materials were used to make it easier and cost effective.
