SECTION ASSESSMENTS Homework - Semester AY 2020 - 2021 Moving Forward A beam has a bending moment of 2 kN-m applied to a section with a hollow circular cross-section of external diameter 3.9 cm and internal diameter 2 cm. The modulus of elasticity for the material is 210 x 10° N/m2. Calculate the radius of curvature and maximum bending stress. Also, calculate the stress at the point at 0.8 cm from the neutral axis Solution: (i) The moment of inertia = ii) The radius of curvature is (iii) The maximum bending stress is iv) The bending stress at the point 0.8 cm from the neutral axis is

Hey hows it going, this is a problem from my Structural Analysis course. I am havinig trouble understadning dead loads on girders. The solution is posted on Bartleby. For the dead loading acting on the girder AG, the solution only accounted for the weight of the girder itself. This does not make sense to me because doesnt the girder also support a portion of the concrete slab? Thanks!

A built-up section is used as a structural member for a two-storey structure. Two channels and angle bars are to be welded to a rolled W section as shown. Determine the following if every section have dimensions in inches equal to : a= 11.10, b= 3.05, c= 0.50, d=3 , e=1/2, f=18.60, g=11.10, h= 0.535, i= 0.87 * Compute the section modulus of the composite section: Use S= Ix/ c, where Ix = moment of inertia of built up section, c= distance from neutral axis to the topmost/ bottommost fiber of the built up section. Compute the radius of gyration with respect to the x-axis  Centroidal moment of inertia with respect to the y-axis. Centroidal moment of inertia with respect to the x-axis. Compute the radius of gyration with respect to the y-axis pls help me solve this (T___T) P.S : 3 decimal places
