sketch a 9 bar parallel chord plane truss with rectangular panels, having 2 diagonal bars, 3 vertical bars, and two bars in each chord(too and bottom). Each panel is 3ft high and 4ft wide and the two diagonal bars are parallel. the truss is supported with a roller and a hinge at the corners at the base. a vertical downward load of 60k is applied at the top middle joint. identify all zero force bats and show the reactions at the supports.

2) determine the magnitude and nature of all the other bar forces in the panel to the left or right in the above problem.

Sketch the graph of the function ?(?)= (2x2-5x+2)/(x+1)2, given the derivatives: ? ′(?) = (9?−9)/(?+1)3 and ? ′′(?) = (36?−18)/(?+1)4 Your sketch should consider the following: ● x- and y-intercepts, if any. ● Horizontal and vertical asymptotes, if any. (Show the computation of any relevant limit.) ● Intervals over which ?(?) is increasing/decreasing. ● Intervals over which ?(?) is concave up/down. ● Relative (local) maximum/minimum points and points of inflection, if any. Identify these clearly on the sketch.
