Q2: Consider the truss shown in Figure 2. Two loading cases are applied to the joints: (1) approximately 3 kg of load applied at joint "E", (2) approximately 1.5 kg of load applied at joint "D" and approximately another 1.5 kg load applied at joint "F". The trusses have six load cells attached to the struts, as depicted in Figure 2 by the shaded rectangles 1-6. The struts are connected through hinges at the joints. Please observe the lab carefully and record data from the loading cells. (a) Construct the Free Body Diagram (FBD) for the entire truss in Figure 2 and calculate the supporting forces at point "A" and point "I" for these two cases. According to the calculation results of the two cases, discuss the impact of loading location. [20%] (b) By using the method of sections, calculate the forces in the struts with the load cells (1-6) attached for these two cases.
