The three forces shown are required to cause a horizontal resultant acting through point $A$. If $F$ = 316 lb, determine the values of $P$ and $T$.
Hint: Apply $M_R = \Sigma M_B$ to determine $R$, then $M_R =\Sigma M_C$ to find $P$, and finally $M_R = \Sigma M_D$ or $R_y= \Sigma F_y$ to compute $T$.
