DIAGRAM SHEET $1,$ FIGURE $2($attached$)$ shows a steel beam supported on TWOreactions, $9$ metres apart, then extends a further $2$ metres to form a balcony. The steelbeam will be required to carry THREE point loads and TWO uniformly distributedloads.Select a suitable I$-$section parallel flange steel beam to ensure the building is safe.Use the following scales:Load diagram: $140$ mm $=11$ mShear force: $2$ mm $=1$ kNBending moment: $3$ mm $=1$ kN$.$mThe permissible bending stress for grade $43$ mild steel is $160$ MPa.The maximum shear stress must not exceed $100$ MPa$\mathrm{.}2\mathrm{.}1$ Calculate the value of the reactions at RL and RR$.(4)2\mathrm{.}2$ Determine the values of the shear forces at each intersection. Draw the shearforce diagram. Insert all the values on the diagram. $(4)2\mathrm{.}3$ Calculate and draw the bending moment diagram. Insert the value of thebending moment's maximum in the diagram. $(6)2\mathrm{.}4$ Calculate the maximum section modulus for the loaded beam. $(3)2\mathrm{.}5$ Select a suitable I$-$section parallel flange for the loaded beam from the BOE$8/2$ steel tables. $(1)2\mathrm{.}6$ Calculate the maximum shear stress in the chosen steel beam which shouldnot exceed $100$ MPa.
