Identify the maximum load intensity w0 that can be applied if the weld can resist a maximum shearing stress τallow of 90 MPa. Given that the centroid ?̅ of the beam is located at 110.485 mm from the base of the beam.
Extracted text: The simply supported beam shown in Figure 4(a) is subjected to uniformly varying load having a maximum intensity of wo N/m at the right end of the beam. The cross-section of the beam has a double T profile, with dimensions as illustrated in Figure 4(b). The double T-beam is fabricated by welding the three plates together.
