In a laboratory test of a beam loaded by end couples, the fiber at layer AB as shown are found to increase 40 x 10 -3 mm while those at CD decrease 70 x 10 mm in the 240- mm-gage length. Using E = 150 GPa, determine the flexural stress at the top fiber. Answer must be in MPa. Given: a = 50 mm, b 140 mm, andc = 90 mm. !! gage length a mm A B. b mm C mm
