What is necking in tension test?
Necking is the localized reduction in cross-sectional area of a material subjected to a tensile force during a tension test. It usually occurs just before the material fractures. This deformation can be observed as a decrease in diameter in a tensile specimen.
What is the duplication and equal division of a cell's genetoc material?
Duplication of genetic material occurs during S phase of the cell cycle, where DNA is replicated to form two identical copies. Equal division of genetic material happens during mitosis, where replicated chromosomes are separated into two daughter cells during cell division to ensure each cell receives a complete set of genetic material.
How do the meanings tell you what happens during photosynthesis?
The meaning of photosynthesis is synthesizing food material by using light.light and co2 are used turn glucose in soluble forms during day time.
How does mylonite form?
mylonite is fromed by two of the eaths plates slideing on top of each other and one of the plates gets pushed down and the rocks on the plate that is getting pushed down to so it terns to magma then a valcano erups and the lava dries and terns to rock.
What happens chromosomes undergo crossing-over?
During meiosis, permutation.
Why the machining of brittle material is easy than ductile material?
Very ductile material will often smear rather than cut during machining operations. Less ductile material (more brittle) will cut more easily.
What conditions do rocks exhibit ductile deformation?
Rocks exhibit ductile deformation when they are under high temperature and pressure conditions, allowing them to flow and deform plastically instead of fracturing. This occurs mainly in the deeper parts of Earth's crust where temperatures and pressures are higher, such as in the mantle or during mountain-building processes. Rocks that are more ductile, such as shale or marble, tend to undergo this type of deformation more readily than brittle rocks like granite.
What is flow stress?
flow stress is yield stress of material during plastic deformation
What is plastic deformation?
Plastic deformation is a permanent unrecoverable deformation. When the load that caused the deformation is removed, the material will not return to it's original shape but will maintain it's newly deformed shape.
What is the importance of tests?
Impact test determines the amount of energy absorbed by a material during fracture. This absorbed energy is a measure of a given material's toughness and acts as a tool to study temperature-dependent brittle-ductile transition. It is to determine whether the material is brittle or ductile in nature.
A student studies an unknown material during a science experiment She discovers that the material is ductile and can conduct heat and electricity She can identify the substance as?
There are a quite a few answers that fit this question. Gold is very ductile and is an excellent conductor of heat and electricity.
During metamorphism the material undergoing deformation remains a solid?
During metamorphism, solid rocks are subjected to high temperature and pressure conditions, causing them to recrystallize and change mineralogy without melting. The material undergoes deformation through solid-state processes, such as plastic deformation and grain rotation, while maintaining its solid state.
What happens if someone lies about you during your security clearance investigation?
You can sue them for deformation of character. It is also another crime.
What are causing the sounds from barbecue hotplates when they are first heated or when they cool down?
When the barbique hot plates are heated or coolede down, due to the change in temperature there will be a minor deformation of the material. During this small deformation, the sounds occur.
What is the importance of impact test?
Impact test determines the amount of energy absorbed by a material during fracture. This absorbed energy is a measure of a given material's toughness and acts as a tool to study temperature-dependent brittle-ductile transition. It is to determine whether the material is brittle or ductile in nature.
What happens to the volume of a material during thermal contractions?
It becomes smaller.
How can one determine the shear modulus of a material?
The shear modulus of a material can be determined by conducting a shear test, where a force is applied parallel to the surface of the material to measure its resistance to deformation. The shear modulus is calculated by dividing the shear stress by the shear strain experienced by the material during the test.
