Question

a) Find the reactions(10 points) b) Draw the shear diagram (10 points) c) Draw the moment diagram(15 points) d) Calculate the moment of Inertia of the cross-section about its x-x neutral axis using the parallel axis theorem and compare this to the Onesteel value. Do the two values agree? (20 points) e) Determine the maximum tensile bending stress and indicate its location in the section (15 points) f) Calculate the maximum shearing stresses in the cross-section and draw a profile of these shearing stresses showing their magnitudes at the critical points (20 points) g) Analyse the top half of the Universal Section allocated to you, so it becomes a T- Section, and use the 1st moment of area method.)-Σ to find the Centroid of dA ATotal the T- Section relative to axis x-x. (10 points) 30kN Uniform Load 8kN/m 2 metres 3 metres metres 8 metres On the following page is a table listing the Onesteel Universal Section allocated to each student. Each student is required to use the Onesteel catalogue table to obtain the dimensions and properties relevant to the solution of questions a) to g) above Mechanics of Structures 2 Assignments2 2018.doc
