In a laboratory test of a beam loaded by end couples, the fiber at layer AB as shown are found to increase 30 x 10 3 mm while those at CD decrease 60 x 10 mm in the 280- mm-gage length. Using E= 150 GPa, determine the flexural stress at the bottom fiber. Answer must be in MPa, Given: a 50 mm, b - 120 mm, and c - 80 mm. gage length a mm b mm c mm
