Three coplanar concurrent forces act as shown.

(a) Calculate the moment of each force about point O that lies in the line of action of the F1 force.

---

(b) Calculate the algebraic summation of the three moments about point O and determine the sense of the moment sum.

---

(c) Calculate the magnitude of the resultant and angle of inclination with the X axis.

---

(d) Compute the moment of the resultant about point O and compare with the result of part (b).
