A crane is lifting a container at Point AAA in $3$D space. The crane is subjected to multiple forces due to wind, cable tension, and weight distribution. The forces acting on the crane are: $1.$ Force $1$: F$1=(50$ i $-30$ j $+40$ k$)$ N is applied at Point B $(2,4,0).2.$ Force $2$: F$2=(20$ i $+45$ j $+10$ k$)$ N is applied at Point C $(3,1,2).3.$ Force $3$: F$3=(25$ i $15$ j $20$ k$)$ N is applied at Point D $(1,5,1).4.$ Additionally, a moment of M $=(8$ i $+12$ j $6$ k$)$ Nm is acting about Point A $(0,0,0).$ Find the equivalent force and moment system at Point A$.$
