# Shear Modulus - Steel

## 1.   Normal Temperature Dimensioning

Shear modulus describes the material's ability to resist shear forces. Other names of shear modulus are sliding factor, modulus of rigidity, coulomb modulus

Young's modulus of elasticity  E         21 000 kN/cm2

Shear modulus G

G  = E / (2 x ( 1 + v))
G = 8 076 kN/cm2

Poisson's ratio v in elastic range                  0.3

Density ρ                                                   7 850 kg/m3

## 2.   EP-Calculation

G = 21 000 /1.6182 kN/cm2
G = 8 021 kN/cm2
(G = 80 200 N/ mm2)

Several tables have the value of 8.000 kN/cm2 or the similar value (Gpa or N/mm2)

Density ρ                                       ρ =    7 850 kg/m3

ρ = 1.618 / (2 x 1.0328)

ρ = 0.783 kg/dm3

## 3.   Calculation is Based on

Momentum p is transformed into Lorenz - variant factor 1/L when L = sqrt (1-( v/c )2)
==>    time dilation 1.0328 when the speed of light 0,25 c

1d x 2d x time dilation = 1.618

1.25 x 1.25 x 1.0328 = 1.618

1d x 2d x 3d x time dilation = 2

1.25 x 1.25 x 1.25 x 1.0328 = 2

## 4.   The Theory of Proportionality

4.1   One hundred years after the general theory of relativitythe theory of proportionality explains how the identified astronomical scale matters affect at low speed phenomena on the Earth. This is shown in EP-Calculation.

4.2   One of the greatest scientific fallacy has been time dilation accession taking place only at a high speed phenomena. Athletic racers running on the track have the same status under the universal law, than the maximum speed rocket has. Any real rocket close to the speed of light rocket, might never be able to produce. In this time calculation in materia having any space rocket speed.
