A steel cantilever beam, of length 21, has an I-section, see Figure Q3. The cantilever beam is under a uniformly distributed load q = 185 kN/m applied in its vertical plane of symmetry at OA part of the span. The yield strength of the steel is [0] =360 MPa; the Young's modulus E = 240 GPa. L=1m and the coordinates of Point H are x= 0 mm, y = -60 mm, z= 0 mm.
