Q$2$

Consider the truss shown in Fifure? Two loading rases are apnitied to the joints $($I$)2kg$ of load applied at iont $"E",(2)1kg$ of loari apptict at joint $"D"$ and another $1kg$ load applied at joint $"F"$

The trussec have six laad cells attached to the struts, as depicted in Figure $2$ by the shaded rectangles $1-6.$ The strits are connected through hinges at the joints. Please observe the lab carefully and Foord data from the loading cells

$($a$)$ Construct the Free Body Diagram $($FBO$)$ for the entire truss in Figure: $2$ and calculate the supporting forces at point $"A"$ and point $"1"$ for these two cases According, to the calculation results of the two cases, discuss the impact of loadinglocation.

$[20\%]$

$($b$)$ By using the method of sections, calculate the forces in the struts with the load cells $(1-6)$ attached for these two cases.

$[2050]$

$($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 vour analytical results at load cells $(1-6)$ with the experimental measurements for the two loading cases.
