CONSTRUCTIVE PROVISION INTRODUCED TOGETHER FOR THE STUDY OF THE PROPORTION BETWEEN A CIRCUMFERENCE ARC OF DISCS FACING THE FUNCTION OF THEIR RESPECTIVE DIAMETERS

摘要

Constructive arrangement introduced together for the study of the proportion between the measurement of a disk circumference arc according to its respective diameters. The utility model deals with a jointly introduced constructive arrangement for the study of the proportion between the measurement of a disk circumference arc according to its respective diameters,Located in the technological sector of equipment for teaching and Research on mathematical relations,More specifically,Relationships of geometric proportions.That currently,There is no equipment designed to carry out practical and accurate readings of wheel pattern perimeters and diameters,Hindering studies with the aim of establishing the geometric relations of the PI constant;Since improvised solutions are adopted,Not by setting up a standardized set of use for conducting more appropriate studies as required didactically.Is characterised by comprising a set of disks (1) with differentiated diameters and handle (2) with different types of angular scales (3) in conjunction with ruler (4),Which is endowed with different linear scales (5).
