To lower ends of the three bars in the figure two are the same level before the rigid homogeneous W=176kN block is attached. Each still bar has a length of 1.00 m, an area 500mm² and E=200 GPa. For the bronze bar the length is 1.6m, the area is 900mm² and E= 83 GPa. What is the stress developed in the bronze bar? What is the stress developed into steel bar? What is the elongation of each bar?
