Unformatted text preview: A steel plate is acted upon by ‘two couples as shown. Determine mthe moment of the couple formed by the two 40-N forces, flthe value of a if the resultant of the two couples is 3 N - m counterclockwise and: d = 820 mm, (c) the perpendicular distance between the two 24-h? forces if the resultant me two couples is zero.
