2D truss moments orthogonal components 01

a	b	c	d	$F_{C_x}$	$F_{C_y}$	$F_{D_x}$	$F_{D_y}$
5.9 m	7.7 m	4.5 m	6.8 m	4 kN	19 kN	14 kN	11 kN

A truss has orthogonal force components applied to it at C and at D as shown. Given the dimensions and force components shown in the table, find the moments that the force components create about joints A and B.

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.)

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