The modulus of elasticity is calculated by dividing the stress by the strain, where . M = modulus of elasticity (ISO 9856) F = force (N) ε elast = elastic elongation at the end of the specified number of cycles (N/mm). In other words: The higher the modulus the lower the elastic elongation per unit stress.

Starting around 1900, mechanization was applied to this method. By 1940, some referred to longwall mining as "the conveyor method" of mining, after the most prominent piece of machinery involved. Unlike earlier longwall mining, the use of a conveyor belt parallel to the coal face forced the face to be developed along a straight line. The only other machinery used was an electric cutter to ...

· Figure 7 shows a particular known type of vertical screw conveyor used at a port facility for unloading coal from bulk ships. The screw conveyor is forced fed by means of a counter rotating lower casing with feed vanes as illustrated. Hence the capacity of the screw conveyor is controlled by the feeding device and not by the conveyor itself.
