What happens to strain when stress is increased in a material?
It also increases. It increases linearly with stress in the elastic range, then increass more rapidly once the material is plastic ( yielded).
What strain or pressure in a material due to forces acting on it?
Stress
What does it mean if you have a high value for youngs modulus 8333.3 compared to a low value 1200?
Young's modulus is stress/strain. So if the modulus is high, it means that the stress value is greater compare to that of the material where the modulus is low. or in other words, the strain is very less compared to that of the material having low Young's modulus. So it tells that, if a material has high Young's modulus, the material requires more load for deformation of shape (within elastic limit).
What is relastion between strees and strain?
no because stress depends on the force and area of the element
What is the greatest stress that material can resist before breaking?
The greatest stress that a material can resist before breaking is called the ultimate tensile strength. It is the maximum amount of stress a material can withstand without breaking under tension. Different materials have different ultimate tensile strengths, and it is an important property to consider for designing and engineering structures.
What is the Formula for Hoop stress?
Hoop stress is just nothing but stress which can be acted upon circumferentialy formed material, where as subjected to internal & external pressure. Formula is (internal pressure*outside dia of cylinder)/internal dia of cylinder If innternal pr goes beyond 80mpa, this presuure vessel is in safer side
What is a hoop stress?
The hoop stress is the force exerted circumferentially in both directions on every particle in the cylinder wall.
Is hoop a noun?
Yes the word 'hoop' is both a noun (hoop, hoops) and a verb (hoop, hoops, hooping, hooped).The noun hoop is a word for a circular band made of rigid material, a word for a thing.The verb to hoop is to surround, support, or bind with a hoop.
What does fatigue mean in a material?
Fatigue in a material refers to a weakening or degradation of the material due to repetitive loading or stress cycling over time. This can lead to cracks, fractures, or failure in the material even if the stress levels are below the material's ultimate strength.
How can one calculate strain from stress in a material?
To calculate strain from stress in a material, you can use the formula: Strain Stress / Young's Modulus. Stress is the force applied to the material, and Young's Modulus is a measure of the material's stiffness. By dividing the stress by the Young's Modulus, you can determine the amount of deformation or strain the material undergoes under the applied stress.
Cite an example of an object that has CG where no physical material exists?
A hula hoop.
How to find strain from stress in a material?
To find strain from stress in a material, you can use the formula: Strain Stress / Young's Modulus. Young's Modulus is a measure of the stiffness of a material. By dividing the stress applied to the material by its Young's Modulus, you can calculate the resulting strain.
What is the maximum amount of stress a material can exert called?
The maximum amount of stress a material can exert is called the ultimate tensile strength. It is the maximum stress a material can withstand before breaking.
Critical stress at which material will start to flow?
The critical stress at which a material will start to flow is called the yield stress. It represents the point at which the material transitions from elastic deformation to plastic deformation, causing it to permanently deform under applied stress. Yield stress is an important mechanical property that determines the material's ability to withstand deformation.
Example of an object that has a CG where no physical material exists?
a hula hoop, a ring, a doughnut
In which factor does breaking stress depends?
Breaking stress of a material depends on factors such as the material's type, structure, temperature, and loading rate. It measures the maximum stress a material can withstand before breaking.
What is the relationship between normal stress and shear stress in a material under mechanical loading?
Normal stress and shear stress are two types of stresses that act on a material under mechanical loading. Normal stress is a force applied perpendicular to the surface of the material, while shear stress is a force applied parallel to the surface. The relationship between normal stress and shear stress depends on the material's properties and the direction of the applied forces. In general, normal stress and shear stress can interact and affect each other, leading to complex mechanical behaviors in the material.
