Two steel wires, each having a cross-sectional area of 2 mm² are tied to a ring at C, and then stretched and tied between the two pins A and B. The initial tension in the wires is 50 N. If a horizontal force P is applied to the ring, determine the force in each wire if P = 20 N. What is the smallest force P that must be applied to the ring to reduce the force in wire CB to zero? Take σ_y = 300 MPa. E_st = 200 GPa.
