Avaliação da força de tração em carroças agrícolas submetidas a diferentes cargas verticais em diferentes superfícies e inclinações.

Abstract

The objective of this work went evaluate by force of necessary traction to move agricultural coaches submitted to different vertical loads in different surfaces and inclinations of the land. This work was accomplished in the region of Lages, because a lot of families have as main middle of support the transport of products and agricultural input and the collection of materials also recycled, accomplished through the animal traction. In this work the experimental design was used in blocks, tends in the portions the surface conditions (hard ground, brick and asphalt), in the split plots the vertical loads (2000, 4000 and 6000N) and in the split split plots the inclination angles (0o, 22,5o and 45o), with five repetitions. The results showed that as it increases the inclinations of the surface and the vertical loads, it also increased by force of necessary traction to move the wagon. It is the surface of hard ground with larger vertical loads than 2000 N presented larger resistance to the rolling.
