= A steel cantilever beam, of length 2L, has an l-section, see Figure Q3. The cantilever beam is under a uniformly distributed load q 200 kN/m applied in its vertical plane of symmetry at OA part of the span. The yield strength of the steel is [o] = 420 MPa; the Young's modulus E = 240 GPa. L= 3 m and the coordinates of Point H are x= 0 mm, y = -65 mm, z= 0 mm.
