4. The lower ends of the three bars in Fig. 3 are at the same
level before the rigid homogenous 28 Mg block is attached. Each
steel bar has an area of 600 mm2 and E = 200 GPa. For the bronze
bar, the area is 900 mm2 and E = 83 GPa. a) Determine the stress
developed in the steel bar. b) Determine the deformation of the
bar.
