material Flashcards
Today, flat glasses are made by ……. In this method, the glass dough is passed horizontally over the molten tin pool
Float Technique
What is it called when stress ( o ) and deformation ( E ) are proportional
Elastic Deformation
Which material feature is referred to as the loss of parts on their surfaces due to their hardness as a result of the contact of two objects in motion. Factors such as pressure and interaction time applied in the material are also effective in this event that causes surface deterioration in the material.
Abrasion
Which is the feature of concrete material
It is brittle.
Objects can also be deformed by the effects of two parallel and opposite directional forces relative to any axis. This condition is called ………. Stress
Shear
In the reinforced concrete structural element, which is a composite material, concrete meets ……., stresses, while steel meets ……… stresses
Compressive / Tensile
Which is the feature of glass material?
It is resistant to compressive stresses.
………… is the ratio of the weight of the material to the volume without pores after the pores have been removed.
Density
……. Is the case where the proportional change between stress and deformation disappears and the shape change of the material is permanent.
Plastic deformation
What is it called when stress and deformation are proportional?
Elastic deformation
Which is not a natural stone production method?
Tempering
Concrete is a mixture of …….
Cement, Aggregate, Water
According to the Mohs scale, which of the following material is the hardest one?
Diamond
What is the inorganic based material with amorphous structure, whose main substance is silicon dioxide. Which shows the properties of liquid objects as well as the mechanical properties of solid objects?
Glass
Identification and classification of concrete is done according to ………
Compressive Strength
Which is the feature of the material with a crystalline internal structure?
It transmits heat, electricity and sound.
What is the glass material that has high strength produced by placing the plastic film layer ( pvb ) between at least two glass panels ?
Laminated glass
The amount of deformation that occur against the temperature difference of any material of a certain length is observed in each material in different amounts depending on the internal structure of the material. In this equation; ΔI= a.I.Δt, the a value is called as ……..
Expansion coefficient.
