Acylindrical bar of metal having a diameter of 18.4 mm and a length of 192 mm is deformed elastically in tension with a force of 52400 n.
given that the elastic modulus and poisson's ratio of the metal are 64.0 gpa and 0.32, respectively, determine the following:

(a) the amount by which this specimen will elongate in the direction of the applied stress.

(b) the change in diameter of the specimen. indicate an increase in diameter with a positive number and a decrease with a negative number.

Agas contained within a piston-cylinder assembly e end nation about same energy states, 1 and 2, where pi 10 bar, v undergoes two processes, a and b, between the sam 0.1 m3, ui-400 kj and p2 1 bar, v2 1.0 m2, u2 200 kj: process a: process from 1 to 2 during which the pressure- volume relation is pv constant process b: constant-volume process from state 1 to a pressure of 2 bar, followed by a linear pressure-volume process to +20 0 state 2 kinetic and potential energy effects can be ignored. for each of the processes a and b, (a) sketch the process on p-v coordinates, (b) evaluate the work, in kj, and (c) evaluate process the heat transfer, in kj
