ABSTRACT: Thesis/Objective – the issue of evaluation of university mobile services has not been broadly explored, especially in Poland. Such research is worth conducting, as more and more users of library websites – students in particular – use mobile devices while searching required information.

This article describes a new laser systems to measure the Young’s modulus of a long fibre based on the diffraction of light. Two setups are presented. The first setup has been used to measure the static Young’s modulus of a thin basalt fibre (10μm diameter, 93mm length). The second setup called “impulse mechanical spectrometer” was used to measure the dynamic Young’s modulus of a long polyamide fibre...
