A steel rod with length equal to 12 ft, has a diameter of 0.8 inches in quarter of its length and a diameter of 0.4 inches the rest. If it is subjected to a tensile load of 6,500 lbs, what will be the total deformation of the bar if it has a modulus of elasticity E = 29.5 10^6 psi.

Problem 7 The shear stress-strain diagram for an alloy is shown in the figure. If a bolt having a diameter of 0.25 in. is made of this material and used in the lap joint, determine the modulus of elasticity E and the force P required to cause the material to yield. Take v=0.3. 7 (ksi) Ty= 50 0.004 y (rad)

8-21. The elastic portion of the stress-strain diagram for an aluminum alloy is shown in the figure. The specimen from which it was obtained has an original diameter of 12.7 mm and a gage length of 50.8 mm. When the applied load on the specimen is 50 kN, the diameter is 12.67494 mm. Determine Poisson's ratio for the material. 8-22. The elastic portion of the stress-strain diagram for an aluminum alloy is shown in the figure. The specimen from which it was obtained has an original diameter of 12.7 mm and a gage length of 50.8 mm. If a load of P = 60 kN is applied to the specimen, determine its new diameter and length.
