1. Three forces are applied to a mechanical link as shown. 300 lb 500 lb 30⁰ 4 3.00 45° y O ALL DIMENSIONS IN INCHES 200 lb -5.00- 3.00 + 3.00 X (30 points) a) Express the 500 lb force as a vector in terms of the unit vectors i and j. b) For the force system (three forces) shown, determine an equivalent force-couple system acting at the origin (point O). In expressing your answer, write the force vector in terms of i and j components, and indicate the magnitude and sense (CW or CCW) of the couple. c) If the given force system is to be represented by a single force, determine the coordinate of the point on the x-axis through which the line of action of this resultant would pass.
