Structural modification of the suction cup is presented with a bearing supporting plate having a material with an adhesion layer [1, 2, 3, 4] on the contact boundary and allowing the down-pressure to be regulated depending on mechanical properties of the object kept.
So distributed loading brings marked changes in the contact area geometry (contact profile shape) owing to the elastomer friction, adhesive and material properties and the vacuum degree.
These changes affect very much the contact stability, and finally they can lead up to the collapse of gripping [5, 6, 7].
In this way an optimal level of the down-pressure can be achieved depending on a deformation of the rim 2, mechanical properties and the surface profile of the object 7 and so a maximum grow of friction forces during handling can be provided.
The function element has not been tested in a dusty or dirty environment and it can be assumed that the contaminated surface will negatively affect the level of the gripping forces.

Critical stress/strain is an important parameter to describe the transport property of superconductors under mechanical stress.
Thus, it is indispensable to study the transport property of superconductive wires under mechanical stress/strain.
Here the electrical transport property of copper reinforced Bi-2223/Ag tape under mechanical tensile stress was studied at 77 K.
Thus, when the mechanical property in HTS tapes is studied, the random of choosing samples should be also considered.
The further study will be needed on the relationship between the mechanical property of HTS tape and the mechanical property of its components to locate the critical stress/strain in the stress-strain curve.

Due to this fact, it is important to recognise the impact of welds on the properties of manufactured structures.

Introduction Nitrile-Butadiene Rubber (NBR) has good mechanical properties and abrasion resistance, particularly it has been used as a generic oil resistance of rubber, and it’s widely used in automotive, aerospace, oil and mining industries [1].
NBR is the random copolymerization of butadiene with acrylonitrile (ACN), the mechanical properties and oil resistance enhanced, cold resistance dropped with the content of ACN increased.
NBR with high acrylonitrile content, such as DN-219, N-32, shows good oil resistance and mechanical properties and their low-temperature properties can be improved by adding additives or chemical modification.
They both can improve the mechanical properties of the coating, especially the phenolic resin can improve the cold resistance in some way.
The NBR cured with composite curing system possessed best physical mechanical and cold resistance properties.

For flat products the requirements on good flatness and surface quality can also be as important as the requirements on mechanical properties but this aspect is not discussed further.
The factors given by Murota et al [5] can be used in most cases.
For higher grade steels more carbon and other alloying additions has to be added for attaining the required mechanical properties.
Alloying content tied up as carbides or nitrides cannot contribute to the hardenability and coarse precipitations can sometimes even cause deterioration of the mechanical properties.
Hence the steel composition and QT parameters can be chosen without a requirement on mechanical properties after stress relieving.

Its physical properties are similar to those of petroleum diesel, except that it has negligible sulfur content, which makes it a cleaner fuel alternative.
Theoretically, many factors affect torque.
Since the experiment was performed under controlled conditions, the remaining factors that will be investigated are engine speed and fuel composition.
Data Analysis and Discussions From the experimental data obtained, analysis was made using the biofuel blend and engine speed as factors against the engine torque, power and fuel consumption.
Further analysis may be needed to explore other chemical and mechanical factors.
