Resumen

DIEGO NAVA, Fidel; HERRERA SUAREZ, Miguel; GARCIA DE LA FIGAL COSTALES, Armando Eloy  y  MARTINEZ Y CARDENAS, José Rodolfo. Force systems analysis from the mexican wooden ard work. Rev Cie Téc Agr [online]. 2015, vol.24, n.1, pp.29-37. ISSN 2071-0054.

The use of wooden plough with oxen is widespread in the milpas of Central Valleys of Oaxaca. The ploughmen often have problems with the operation of this plough since this has problems of instability during the furrowing. For this reason, the photos were taken during the furrowing with the purpose of watching the ploughman handling during tillage. Then, these data were analyzed for establishing the free body diagrams of the plough. Therefore, it was got four free body diagrams and their equations of static equilibrium. Consequently, the wooden plough was tested for obtaining the draught force through tillage and so doing the relation between actual and computed draught forces. The results show the high draught forces variability in the two circumstances. Finally, it is found that the ploughman handling is related to the high and low draught forces.

Palabras clave : forces; equilibrium; stability; handling.
