The mechanical properties of industrial plexiglas (polymethylmethacrylate) of various sizes (lengths, widths) have been studied when tested for plane straight bending with one concentrated force in the middle of the sample. By a result of the experimental work, the relationship between deformation and stress was obtained. It is clearly shown in the work that the experimental curves substantially depend on the parameters of the starting materials and are satisfactorily described by a linear model. The slope of tangent (α) for the curves ranges from 0,32 to 0,62%MPa-1. The dependence of a α on the length and width of the samples changes significantly. Moreover, the maximum deformation varies in the range of 50 – 60%, which confirms the dependence of the deformation properties of the material on horizontal components, in particular, on the length of the sample. The tensile strength of the material also differs between specimens of different sizes.
