The $($Figure $1)$ shows two thin beams joined at right angles. The vertical beam is $16\mathrm{.}0$ kg

and $1\mathrm{.}00$ m long and the horizontal beam is $21\mathrm{.}0$ kg and $2\mathrm{.}00$ m long. Neglect the lateral dimensions of the beams. A$)$ Find the center of gravity of the two joined beams. Express your answer in the form x$,$y$,$ taking the origin at the corner where the beams join. B$)$Calculate the gravitational torque on the joined beams about an axis through the corner.
