Consider the truss shown in Figure $2.$ Two loading cases are applied to

the joints: $(1)2$ kg of load applied at joint $$E$,(2)1$ kg of load applied

at joint $$D$$ and another $1$ 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.

$[20\%]$

$($c$)$ Tabulate the results of both the calculation and the measurement

for the two cases. Provide a short discussion of the experimental

laboratory for the truss in Figure $2($half a page maximum$)$ and

compare your analytical results at load cells $(1-6)$ with the

experimental measurements for the two loading cases

CAN YOU PLEASE PROVIDE DETAILED CALCULATIONS FOR ALL THE PARTS. I AM HAVING TROUBLE IN ANSWERING THEM
