Figure Q3 (1) shows a cross-section of a different asymmetrical cast iron tee beam with a cantilever span of 2.5m; also see elevation in Figure Q3 (). The allowable bending stresses in the tee beam are shown the table below: Tension Compression Question 3 continues next page...... Question 3 continued.. 15mm + 65mm Maximum stress (N/mm²) 50 100 25mm 180mm Figure Q3 (ii) Section through cantilever tee beam 2.5m Figure Q3 (i) Elevation on cantilever tee beam The geometrical properties of the tee beam are shown in the table below. Distance of the horizontal neutral axis of the tee beam above 128.5 mm the bottom of the section Second moment of area (1) 1803 cm 34 c) What is the maximum force A that can be applied vertically downward to the cantilever tee beam without exceeding the allowable bending stress in the tee beam (ignore force B)? (10 marks) d) What is the maximum force B that can be applied vertically upward to the cantilever tee beam without exceeding the allowable bending stress in the tee beam (ignore force Aj? (10 marks) Total 40 marks III
