Question

3 Statically indeterminate end-to-end bars. Given: The two-bar structure is fixed at both ends and a 0.01 in. gap exists between the two bars, as shown in Figure 3. Bar l is made of Aluminum 2014-T6, the elastic modulus isEal umum. 6 ksi, the linear coefficient of thermal expansions is αalun in 12.8(10 6) F, and cross-section area of Bar l is Al-05 in. Bars 2 is made of Steel-A36 Structural with Estss 29000 ksi, Qsteel 6.610 A2 0.2 in. Two bars are subjected to temperature changing from T 0°F to T1009E Tofind: The average normal stress in both bars. (when you use MDSolids, go to "Indet Axial" modulus-> Analysis Options""End-to-End Bars" "with Gap in the Middle") Bar 1 しBari-10 in. 0.01 in. LBar2 8 in. Bar 2 Fig 3
