Projeto, constru？？o e teste de um Torcímetro

the torsiometer is a device used to measure the change in angle between two positions and one of its applications is to measure the angle of twist in torsion tests of materials. this paper describes the working principle, the main details of design and construction of a low cost torsiometer. its calibration curve and some experimental results are also shown to quantify the measurements obtained with this prototype.
