A steel cantilever beam, of length 2L, has an l-section, see Figure Q3. The cantilever beam is under a uniformly distributed load q = 250 kN/m applied in its vertical plane of symmetry at OA part of the span. The yield strength of the steel is [a] = 340 MPa; the Young's modulus E = 249 GPa. L = 3 m and the coordinates of Point H are x= 0 mm, y = -85 mm, z= 0 mm. y O L 0 q A L B X Figure Q3 20mm 10mm H 20mm -220mm b 180mm a) The factors of safety predicted at point H by the maximum shear stress theory of failure (Tresca criterion) A steel cantilever beam, of length 2L, has an l-section, see Figure Q3.
