2D truss moments angled forces 01

a	b	c	d	$F_C$	$\phi$	$F_D$	$\theta$
15.7 ft	20.5 ft	11.8 ft	18.1 ft	3.2 kip	54 deg	2.6 kip	65 deg

A truss has forces applied to it at C and at D at the angles shown. Given the dimensions and forces shown in the table, find the moments that these two forces create about joints A and B. Also find the reaction forces at the supports.

Moments: (counter-clockwise positive; clockwise negative.)

$M_A$
$M_B$

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

$R_{A_{horizontal}}$
$R_{A_{vertical}}$
$R_{B_{vertical}}$
