What is the meaning and utility of rf value?
ratio of a distance.
What is the full name of Rf value?
Retention Factor Rf == Distance traveled / total distance
In the electron charge to mass experiment if the electron is replaced by a proton or neutron would the charge to mass ratio value still be the same why or why not?
Compared to the (charge/mass) ratio of the electron:-- The (charge/mass) ratio of the proton is much smaller; although the proton charge is equal to the electron charge, the proton mass is much larger, by a factor of more than 1,800.-- The (charge/mass) ratio of the neutron is zero, because the neutron charge is zero.
Is a Rf value of 0.95 strongly held on the paper or in the solution?
The retention factor, or Rf, refers to the ratio of time an analyte is retained in the stationary phase to the time it is retained in the mobile phase. An Rf value of 0.95 is strongly held on paper than in the solution.
What is the value of distribution coefficient of iodine between water and chloroform?
For Iodine in Chloroform & water, the distribution ratio is 250; hence at equilibrium, the iodine concentration in the chloroform phase is 250 times then in the water phase.
What the Poisson ratio function pressure and process temperature of cured phenolic resin?
Im no vandal nor spammer. i only need the value of poisson ratio of cured phenolic resin(function of pressure and temperature process) for conclude a job and i dont find that information. Thank you, Lindemberg, Brazil.
What is the least expensive but good epoxy resin for boat building?
Mass Epoxy Resin seems to be good value.
What is the value of poisson's ratio?
Poisson ratio of most linear elastic material can be anywhere between 0 and 0.5.
What is the Poisson's ratio value of M30 grade concrete?
0.17
Which material has the highest value of poisson's ratio?
For isotropic materials, Rubber - very close to 0.5
What is the maximum value of Poisson's ratio in strength of materials?
Poisson ratio of most linear elastic material can be anywhere between 0 and 0.5.
What is the value of Poisson's ratio of wood?
Poisson's ratio is the negative ratio of how compression affects distortion. When an object is compressed in one direction it expands in two directions perpendicular to the direction of compression. The ratio is equal to d(transverse strain)/d(axial strain).
What of all materials is most highest value of possions ratio like copper rubber steeel and wood?
rubber is the highest; it is nearly incompressible and results in a Poisson ratio approaching 0.5, the highest possible value.
What is the maximum value of Poisson?
one
What is the value of Young's modulus for epoxy resin?
Epoxy resins have been quoted as having values of Young's modulus in the range of 2-20 GPa.A,BA Ogorkiewicz, R. M. (1973) Linear elastic characteristics of a cast epoxy resin.

What is the poisson ratio for carbon steel?
For Cast Iron, per the related website is: .22 - .30. If you can get more information on the grade of the iron, you will be able to get close to the true value. I have in the past used 0.27 for cast iron.
What are the properties of poisson distribution?
It is a discrete distribution in which the men and variance have the same value.
