Two steel truss members, AC and BC, each having cross sectional area of $100 mm^2$, are subjected to a horizontal force F as shown in the figure. All the joints are hinged.

The maximum force F in kN that can be applied at $C$ such that the axial stress in any of the truss members DOES NOT exceed $100$ MPa is

  1. $8.17$
  2. $11.15$
  3. $14.14$
  4. $22.30$
