84. Which is the false statement about true stress strain method?
85. The change in the unit volume of a material under tension with increase in its Poisson's ratio will
86. A key is subjected to side pressure as well at shearing forces. These pressures are called
87. A riveted joint in which the number otrivets decrease from innermost to outer most rows is called
