In a laboratory test of a beam loaded by end couples, the fiber at layer AB as shown are found to increase 40x 103 mm while those at CD decrease 70 x 10 mm in the 250-mm-gage length. Using E 150 GPa, -3 determine the flexural stress at the top fiber. Answer must be in MPa. Given: a 60 mm, b 120 mm, and c- -80 mm. gage length a mm A 8. b mm c mm
