A steel cantilever beam, of length 2L, has an I-section, see Figure Q2. The cantilever beam is under a uniformly distributed load q = 265 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 = 207 GPa. L = 1m and the coordinates of point H are x=0mm, y=-75mm,z=0mm O q A B X 20mm 10mm H 20mm -220mm b 180mm a) |_z The second moment of area relative to z-axis, I_z, for the cross-section can be calculated as (Enter your answer in cm4 ) b) Sigma The bending stress at Point H can be calculated as (Enter your answer in MPa, Compressive stress is negative and tensile stress is positive) c)SS_z The first moment of area required to calculate shear stress at H can be calculated as (Enter your answer in mm^3) d) Shear stress at H The absolute value of the transverse shear stress at point H can be calculated as (Enter your answer in MPa)
