A weightlifter is holding a $47$ lb weight $(1$ lb is equivalent to $4\mathrm{.}448$ N $)$ with his forearm, as shown in the Figure below. His forearm is positioned at Theta $\backslash (=69\backslash )$ degrees with respect to his upper arm. The forearm is supported by a contraction of the biceps muscle, which causes a torque around the elbow. Assuming that the tension in the biceps acts along the vertical direction given by gravity. What is the magnitude of the force $\backslash (\backslash$mathbf$\{$R$\}\backslash )$ on the elbow joint $($point E$)?$ Assume that the forearm's weight is negligible. Give your final answer in pound $($Ib$).$
