The solid beam shown in Figure 2 is subjected to a concentrated load P at its center. Assume that El is constant for the bear. (a) Determine the support reaction and internal forces from equation of equilibrium with the help of an appropriate free body diagram. (5 marks) (b) Shows the integration to set equation of slope and elastic curve in terms of constants (C, C, C and C) using the boundary and continuity conditions. (6 marks) (c) Determine the equation of the elastic curve for the beam using the x coordinate that is valid for 0 < x < 3m. (7marks) (d) Determine the deflection of end C of the 100-mm-diameter solid circular shaft. Take E = 200 GPa. Figure 2: The solid circular shaft 6 kN (7 marks)
