Question A load of P = 150 kN is supported by a structure consisting of rigid bar ABC, two identical solid bronze [E = 100 GPa] rods (1), and a solid steel [E =200 GPa] rod (2), as shown in the figure. All rods are unstressed before load P is applied to the rigid bar directly underneath joint B. Assume perfect connections at all joints. The bronze rods (1) each have a length of L₁ =2150 mm, a diameter of 40 mm, and a cross-sectional area of 1257 mm². Steel rod (2) has a length of L2 = 1650 mm, a diameter of 30 mm, and a cross-sectional area of 707 mm². Determine the axial force that is produced in steelrod (2) after load P is applied to the rigid bar.
