INSTRUCTIONS:

A beam having a tee-shaped cross section is subjected to equal 18 kN-m bending moments, as shown. Assume b_f = 125 mm, t_f = 25 mm, d = 185 mm, t_w = 20 mm. The cross-sectional dimensions of the beam are also shown.

QUESTIONS:

4) With reference to problem 2, determine the bending stress at point H (positive if tensile and negative if compressive). Express your answer in MPa rounded to the nearest hundredths.

5) With reference to problem 2, determine the maximum bending stress (positive if tensile and negative if compressive) produced in the cross section. Express your answer in MPa rounded to the nearest tenths.
