A Structural System Is Shown In Figure 6 It Comprises A Rigid Beam Ac And Two Unidirectional Fibre Composite Rectangula 1 (450.6 KiB) Viewed 39 times

A structural system is shown in Figure 6. It comprises a rigid beam AC and two unidirectional fibre composite rectangular bars of identical length, width and thickness, AB & CD. The properties of the composite are given in Table 1. The rigid beam AC is pinned at A & C and carries an 800kg steel ball as shown. The dimensions of the composite bars and the beam AC are also shown. For the entire system to function as designed, the steel ball is allowed to displace 0.8mm vertically down and beam AC must be maintained in a horizontal configuration. Determine the required fibre orientation in the composite bars AB & CD for this to happen. The fibre orientation should be determined by both methods and compared with FEA: TO III. IV. Use ANSYS to verify your answers (stress and deflection). (5%) If your Part A test specimen material properties were to be used for the bar, discuss what you believe the effect would be on the structural system.
