The structure has two frictionless pulleys around which a string is wrapped. If $W=56\mathrm{lb}$, determine a force system that is equivalent to the forces applied by the string, where this force system consists of a single force, and specify the $x$ coordinate of the point where the force's line of action intersects the $x$ axis. (Round the final answers to four decimal places. Do not include a minus sign in your response.) The value of $\left(F_R\right)x$ of the equivalent force system is $\mathrm{lb}?$ The value of $\left(F_R\right)y$ of the equivalent force system is Ib $?$. The $x$ coordinate of the point where the equivalent force's line of action intersects the $x$ axis is in.
