inverted cantilevered warren with verticals 01

Given the truss shown, loaded and dimensioned with the values given here:

$\left.\vphantom{\begin{array}{c}\!\strut\\\!\strut\\\!\strut\\\!\strut\\\end{array}}\right[$	$a = 4.2 ft$	$F_1=1000 lb$	$F_3=2040 lb$	$\left.\vphantom{\begin{array}{c}\!\strut\\\!\strut\\\!\strut\\\!\strut\\\end{array}}\right]$
	$b = 6.6 ft$	$F_2=1940 lb$	$F_4=980 lb$
	$c = 8.2 ft$

Find the following, assuming the truss does not deform out-of-plane:
(a) The reaction forces at the supports.
(b) The forces carried in each member.
(c) The minimum required diameter of the tension members, assuming the members have circular cross-sections and are composed of a material that has an allowable stress of 31 ksi. (Enter NA for compressive members)
(d) The change in length of the tension members, assuming they have circular cross-sections with the minimum diameters found in part (c), and are composed of a material that has an elastic modulus of 31000 ksi. (Enter NA for compressive members)

(a)
Reactions:
(If the support applies an upward or rightward force on the structure, enter a positive value, otherwise enter a negative value.)

$R_{E_{horizontal}}$	$R_{E_{vertical}}$	$R_{G_{horizontal}}$	$R_{G_{vertical}}$

(b), (c), and (d)
Members:
(Denote tensile forces with positive values and compressive forces with negative values. Enter NA for the diameters and changes in length of compressive and zero-force members.)
