never heard of a negative modulus. Some special class polymers have negative Poisson ratio so when you pull on it gets wider inserted of narrower, but I know of none that get shorter when you pull on it

What is the modulus of elasticity in stretched wire?
Young's modulus
What is the definition of modulus of elasticity?
applications of modulas of elasticity As the term implies, "Modulus of Elasticity" basically relates to the elasticity or "flexibility" of a material. The value of modulus of elasticity are very much significant relating to deflection of certain materials used in the construction industry. Take for example the general E value of mild carbon steel is about 200 GPa compared to about 70 GPa for aluminum. This simply translate that aluminum is 3 times flexible than steel.
Formula for bulk modulus of volume of elasticity?
K(bulk modulus of elasticity)=-{[Pressure x volume]/change in volume}
What is the difference between Youngs modulus and the modulus of elasticity?
Young's Modulus (modulus of elasticity) describes the stress-strain behavior of a material under monotonic loading. The dynamic modulus of elasticity describes the same behavior under cyclic or vibratory loading.
Is the bulk modulus of elasticity increases with pressure?
Yes, the bulk modulus of elasticity increases with pressure. The bulk modulus measures the resistance of a material to changes in volume under applied pressure. As pressure increases, the material becomes less compressible and therefore the bulk modulus increases.
What is the coefficient of a material's elasticity called?
Young's Modulus
What are the significance of modulus of elasticity and modulus of rigidity in machine design?
IN MACHINE design modulus of elasticity place an important role. from the value of modolus of elasticity we come to know about maximum value of load that can be to the given material upto which the material is assume to follow the hook's law.
What are the different types of modulus elasticity?
there are different types of modulus it depends on what types of stress is acting on the material if its direct stress then then there is modulus of elasticity,if tis shear stress then its modulus of rigidity and when its volumetric stress it is bulk modulus and so on
How do you know the material is elastic?
it depends on modulus of elasticity / young's modulus,,,,,,,which is ratio of stress and strain under elastic limit
How do you calculate stiffness of a elastic material?
When a load is applied to a material it deforms. Elasticity is defined as the ability of a material to return completely to its original state after a load is removed. For example, the reason an elastic band is elastic is that it will return to its original dimensions after being stretched and released. Modulus of elasticity is the measure of this ability and is experimentally determined by measuring how much a material deforms when a given load is applied. A high modulus material is very stiff. A low modulus material is more "rubbery". Engineering calculation of deflection of a design element use Modulus of Elasticity (aka Lambda) an an input.
Is there any effect of temperature on young's modulus of a meterial?
As the Young's modulus is a measure of stiffness, an increase in the temperature will typically lead to a decrease in the modulus of elasticity. However it depends on the material.
What will be the young's modulus if i use two wires both made of copper but they are different in length and diameter?
Young's modulus or modulus of elasticity is a property of the material. As in both the wires we have copper material the young's modulus will be the same. It does not get altered with length or area of cross section.
What determines the slope of a material's stress verse strain curve?
The value of the Young's Modulus of Elasticity, which is an inherent property of the material
Solids liquids and gases. which ones are hard to deform?
When we talk about deformatation, we are referring to two properties, namely Elasticity and Plasticity. These properties are measured using constants known as " Moduli of Elasticity". There are 4 such moduli: Young's Modulus Axial Modulus Rigidity Modulus Bulk Modulus The larger the value of the Bulk Modulus, the harder it is to compress the material.
What is the modulus of elasticity in stretched wire?
Young's modulus
What is the object's modulus of elasticity depends upon?
it does not depends on the material dimensions (cross sectional area and length) and the force exterted on the material. It only depends on nature of the material
What is the dimension of modulus of elasticity?
the dimensions of Young's Modulus of Elasticity = (M).(L)^(-1).(T)^(-2)
