Question 7 Not yet answered Marked out of 2.00 Flag question The cross section dimensions of a metal rod is (0.007 m x 0.007 m), its length is 1000 mm. The allowable stress is 200 MPa. An axial force (longitudinal force) is applied to this rod. 1. The force changes the section dimension to be (0.006 mx 0.006 m), so the type of this force is 2. Due to this change in section dimensions, the new length will be
