In a laboratory test of a beam loaded by end couples, the fiber at layer AB as shown are found to increase 20 x 103 mm while those at CD decrease 90 x 10 mm in the 230-mm-gage length. Using E = 190 GPa, determine the flexural stress at the top fiber. Answer must be in MPa. Given: a 60 mm, b = 120 mm, and c = 70 mm. %3D %3! %3D
