Three horizontal forces are applied to a vertical cast iron arm as shown in the figure. X 02-49:06 150 mm 600 N BOOK 150 mm 400 N 150 mm Determine the resultant of the forces and the distance from the ground to its line of action when P = 320 N. The resultant of the forces (R) is N (Click to select) V The distance from the ground to its line of action (y) is
