Arigid bar with wires at B & C is shown in the figure below. The cross sectional area of the wire at Bis $$3 \times 10^{-4} m^2$$ and at C is $$2 \times 10^{-4} m^2$$. The wires are elasto- plastic with strength 250 MPa and E value 200 GPa. The ultimate load P that can be applied to the rigid bar, as shown is

A

50 kN

B

75 kN

C

100 kN

D

150 kN
