double isosceles 01

Two trusses are arranged to support a set of loads as shown. The dimensions and loads are given in the following table:

Dimensions and Loads:

a	b	$\alpha$	$\phi$	$\theta$	$F_1$	$F_2$	$F_3$
24 ft	31 ft	110 deg	52 deg	27 deg	785 lb	1098 lb	454 lb

Find the force in each member and the reactions at the supports.

Reactions:
(Denote rightward or upward forces applied to the truss as positive; leftward or downward forces applied to the truss as negative.)

$R_{A_{horizontal}}$
$R_{A_{vertical}}$
$R_{G_{horizontal}}$
$R_{G_{vertical}}$

Members:
(Denote tension forces with positive values; compressive forces with negative values.)

Member	Force		Member	Force
$AB$			$GH$
$BC$			$HI$
$CD$			$DI$
$DE$			$DJ$
$AE$			$GJ$
$BE$			$HJ$
$CE$			$IJ$
