Abstract

LA BARRA DE FLEXION (1) PRESENTA DOS AGUJEROS TRANSVERSALES (2, 3) UNIDOS POR UN PARTE VACIADA (4). CUATRO PARTES DEBILITADAS (5, 6, 7, 8) SON ASI FORMADAS EN LA BARRA (1). UNA GALGA DE CONTRACCION CUADRUPLE (9) ESTA FIJADA SOBRE LA BARRA (1) EN EL DERECHO DE UNA (5) DE LAS PARTES DEBILITADAS Y, PARA CORREGIR LA INEXACTITUD DE MEDIDA DEBIDA A LA PRESENCIA DE LA GALGA DE CONTRACCION CUADRUPLE (9) EN UN SOLO DERECHO DE LA BARRA (1), SE HA PREVISTO DOS ENTALLADURAS CALIBRADAS (10, 11) EN EL DERECHO DE LAS OTRAS PARTES DEBILITADAS (7, 8). ESTA DISPOSICION REDUCE EL PRECIO DEBIDO AL USO DE UNA SOLA GALGA EN VEZ DE CUATRO.
