In Figure Q4a, AC is a beam is supported at A and C with a uniformly distributed load of 40 kN/m between A and B. The distance A to B is d₁ with a length of 12.00 m; the distance B to C is d₂ with a length of 6.00 m. The point M is located at the mid-point of the beam AC. A UDL C d1 M B d2 Figure Q4a a) Draw and label the shear force diagram (SFD) for the beam shown in Figure Q4a. Label the values for shear force and bending moment at points A, B, C and at the mid-point M. [7 marks] b) Draw and label the bending moment diagram (BMD) for the beam shown in Figure Q4a and clearly indicate the type of bending that occurs between AB and between BC. On your diagram, clearly show the value of the maximum bending moment and where it occurs along the beam terms of the distance from A. In addition, label the values for bending moment at points A, B, C and at the mid-point M.

The length (L) of the rod is 1.75 m and Young's Modulus for the material (E) is 375 GPa. When the rod is placed under tension it experiences deformation and a stress (σ) of 850 MPa. Calculate the following: (i) Strain energy (U) to 2 decimal places in Joules. (ii) Strain energy per unit volume (U/V) in J/m³.to 2 decimal places. The change in length AL to 2 decimal places in mm. (!!!) (iv) The strain (ε) due to deformation to 2 significant figures. [10 marks]
