A beam having a tee-shaped cross section is subjected to equal 18 KN-m bending moments, as shown. Assume b, = 125 mm, t, = 25 mm, d = 185 mm, t, = 20 mm. The cross-sectional dimensions of the beam are also shown. Use these information to answer questions 6-10. ... H d M Cross section a) Determine the centroid location (measured upward from the bottom), in mm rounded to the nearest tenths. b) Determine the controlling section modulus about the z axis. Express your answer in (10) mm rounded to three significant figures.
