Acylindrical bar of steel 10.3 mm (0.4055 in.) in diameter is to be deformed elastically by application of a force along the bar axis. determine the force that will produce an elastic reduction of 2.9 ×10-3 mm (1.142 ×10-4 in.) in the diameter. for steel, values for the elastic modulus (e) and poisson's ratio (ν) are, respectively, 207 gpa and 0.30. n
