The rigid bar ABC is pinned at B and connected to two steel bars with E = 200-GPa at A and C. Bar (1) has cross sectional area of A= 300-mm and bar (2) has A = 200-mm. After horizontal load P is applied the normal strain in bar (1) is measured to be 8 =+ 910 x 10 mm/mm. Nothing bar (1) is in Tension and bar (2) is in Compression, determine: a- The normal stress and the normal force in bar (1). b- The normal strain, normal stress and the normal force in bar (2). c-Use diagram shown to find permanent deformation in bar (2) if stress reaches to 475-MPa. 2 %3D (1) 2,000 mm o (MPa) 520 mm 500 450 400 mm 1,250 mm (2) (mm/mm) 0.00225 0.03
