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 dimension of bulk modulus?
ml1- t-2
How do you calculate the velocity of the sound?
sound travels at 1126 ft/sec in airto calc in other mediumswhereK is a coefficient of stiffness, the bulk modulus (or the modulus of bulk elasticity for gases), is the density
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.
How fast does sound travel through materials?
Every material has its elastic modulus, and the speed of sound is proportional to the square root of the elastic modulus of that material.
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
If a material has a young's modulus of 220GPa and a poisson's ratio of 0.29 what is its bulk modulus?
The bulk modulus (K) is a material's resistance to uniform compression from all directions. If you have Young's Modulus (E) and Poisson's ratio (ν), the relationship is: K = E/(3*(1-2ν)) For E = 220 GPa and ν = 0.29, K = 174.603 GPa
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.

Bulk modulus of sulfuric acid?
The bulk modulus of a fluid is the measure of its compressibility. In SI units, the bulk modulus of sulfuric acid is 3.0 Newtons per square meter.
Can bulk modulus be used to find the stress-strain relationship of a material compressed in a single axis?
Yes, if the material is very thin in ther axis of compression. If it is not thin, as in compressing a long cyclinder, you do not need to know bulk modulus. If very thin it won't make a lot of difference if it a metal with usual poisson ratio of about 0.25, but will make difference for possion ratio higher, especially approaching 0.5, as in rubber. In the case of the long cyclinder stress = modulus xstrain In the case of the thin material stress = modulus x strain times the quantity (1-u)/ ((1+u)(1-2u)) where u = poisson ratio; the relation to bulk modulus for u is u =1/2 - E/6B where B = bulk modulus and E = elastic modulus
What is bulk modulus and shear modulus for mild steel?
shear = 77GPa
Formula for bulk modulus of volume of elasticity?
K(bulk modulus of elasticity)=-{[Pressure x volume]/change in volume}
How sound waves travel in solid?
Either by volumetric compressions, which are based on the material's bulk modulus, or shear stress (think of a multi-car fender-bender where the first car hits the second, hits the third, etc.) which is based on the material's shear modulus.
What is the dimension of bulk modulus?
ml1- t-2
What two factors effect the speed of sound?
The speed of sound varies with various factors such as temperature,nature of the material,physical state of the substance,etc.
Derivation of the relation between young's modulus and bulk modulus?
E=3k(1-2/m)
