Consider a cylindrical specimen of a steel alloy 8.0 mm (0.3150 in.) in diameter and 89 mm (3.504 in.) long that is pulled in tension. Determine its elongation when a load of 57810 n (13000 lbf) is applied. The tensile stress-strain behavior for this steel alloy is shown in the animated figure 6.22. The answer should be in mm.
consider air in a piston-cylinder assembly. initially the air is at p1 2bars and t1 600k . the air is compressed
a rigid container having a volume of 1.2 m3 contains 10 percent by volume of liquid water at 100 kpa. the remaining
What will be the length of the specimen after the load is removed? d) The specimen was reloaded until fracture. If the % reduction in area after fracture was 40%, what is the minimum diameter of the specimen at fracture?
