a) The truss structure in Figure Q4 is supported at A and D with downward vertical load Fi acting at joint E and a downward vertical load F2 acting at joint C. The length of each truss member AB, BE, BC, CD and CF is 1.25 m. If F 95 kN and F 225 kN, determine the reaction force RA and Ro at the supports A and D. Give your answers in kilonewtons (kN) to two decimal places. F1 F2 Figure Q4 b) For the truss structure in Figure Q4, determine the forces FAE. FAs and For acting in members AE, AB & CF and clearly state if each member is in compression or in tension. Give your answers in kilonewtons (kN) to two decimal places. c) A solid homogeneous truss tie-rod has a diameter of 9.52 mm and an original length of 1.75 m experiences a stress of 600 MPa when placed under tension. If the material used for the truss tie-rod has a Young's Modulus, E, of 5.8 x 10 N/m, calculate: (i) the tie-rod's extension in millimetres (mm): (#) the strain energy (U) in Joules; and (i) the strain energy per unit volume (U/V) in Joules per cubic metre (m). Give your answers to two decimal places.
