(14) An inverted T beam is constructed from a top square cross-section section and a bottom rectangular cross-section of the same length.
The cross-section dimensions of the sections are as follows: -
Top Square Section 30 mm x 30 mm (width x depth)
Bottom Rectangular Section 50 mm x 30 mm
Figure Q14 shows the cross-section arrangement of the plates.
Given that compression and tension behave the same in terms of stress analysis.
Calculate the distance, Ymax, you would use to calculate a safe bending stress value for further analysis.
You are required to state your answer in millimetres to the nearest whole number.
