E (Elasticity modulus) or Y (Young modulus) is an experimentally obtained constant of a material and is a measure of stiffness. For the traction test and the bending test, a force is applied gradually to the specimen, and both force and displacement are measured. These data are in pairs, representing force displacement for bending tests or sigma-epsilon for traction tests. Data introduced by hand are in list inputXY,  data from a CSV file in list inputCSV, and data from Google Sheet in inputGS. 

Data are input generally as lists. Dimensions data are also lists, value is arithmetic mean, useful when a dimension is the arithmetic mean of many measurements.
