A shop sign weighing 210 N hangs from the end of a uniform 180-N beam as shown in (Figure 1) .
Find the vertical force exerted by the hinge on the beam at the wall.
Express your answer to three significant figures and include the appropriate units. Enter positive value if the force is upward and negative value if the force is downward.
I got 10.5N but mastering physics said i was wrong?
