Q1 A truss system is shown in Figure Q1. It is loaded at joints D and E as shown. The truss members are to be manufactured from Aluminium Alloy cylindrical bar with a tensile yield stress of 300 MPa, a compressive yield stress of 200 MPa, and Young's Modulus of 70 GPa. 1.5m 1.5m A B C 4001 10 kN 3m Fig. Q1 E 水 20 KN 1.5m D 키 (a) Show that the truss system can be described as statically determinate. (b) Draw a Free Body Diagram of the truss and determine the reactions at the supports. (c) Use the METHOD OF JOINTS to determine the load in each member of the truss, indicating whether they are tensile or compressive.
