What is the advantage of ductile materials?
Ductile materials can undergo significant deformation before failure, which allows them to absorb energy and distribute stress more effectively. This property makes them ideal for applications where flexibility and toughness are essential, such as in construction and manufacturing. Additionally, ductility enables easier shaping and forming during processing, reducing the likelihood of catastrophic failure and enhancing safety in structures and components.
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 refers to an excess of changes that stay in place on a material?
An excess of changes that remain in place on a material is often referred to as "residual stress." This phenomenon occurs when a material undergoes deformation or alterations during processes like manufacturing or cooling, yet does not fully return to its original shape. As a result, internal stresses can develop, which may affect the material's performance and longevity. Residual stress is crucial to consider in fields like engineering and materials science.
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.
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 happens to the volume of a material during thermal contractions?
It becomes smaller.
