Replace the two forces and one couple acting on the rigid pipe frame by their equivalent resultant force R acting at point O and a couple Mo$.$

Determine:

$1)$ Coefficient of the unit vector i of the resultant force R $($in lb$)$

$2)$ Coefficient of the unit vector j of the resultant force R $($in lb$)$

$3)$ Coefficient of the unit vector k of the resultant force R $($in lb$)$

$4)$ Coefficient of the unit vector i of the resultant force Mo $($in lb$)$

$5)$ Coefficient of the unit vector j of the resultant force Mo $($in lb in$)$

$6)$ Coefficient of the unit vector k of the resultant force Mo $($in lb in$)$

round off to two $(2)$ decimal places

include negative sign $(-)$ if the answer is negative
