Cables 2 and 3 are pulled by 200-N forces. It is desired that the resultant of the forces exerted by the three cables be oriented along the dashed line indicated by the angle 0. Determine the required pull of cable 1 to have (a) 0 = 0, (b) 0 = 20. enoibnoo dw O turtt uidiliups al od orol deiluen on o ma
