Question

8:43 AM loncapa hep.uprm.edu iPad 77%- Points:4 1.25 A shop sign weighing 216 N is supported by a uniform 131 N beam of length L = 1.77 m as shown in figure below. The guy wire is connected D m,from the backboard. Find the tension in the guy wire. Assume = 38.0° 6.47x102 N ou are correct. receipt no. is 158-834 Previous Tries Find the horizontal force exerted by the hinge on the beam. 5.10x102 N You are correct. r receipt no. is 158-6929 Find the vertical force exerted by the hinge on the beam. Use "up" as the positive direction. Submit Answer Find the vertical force exerted by the hinge on the beam. Use "up" as the positive direction. Tries 3/50 Previous Tries Submit Answer Tries 2/50 Previous Tries

Explanation / Answer

net force along vertical = 0

F*sintheta - Wsign - Wbeam + Fy = 0

6.47*10^2*sin38 - 216 - 131 + Fy = 0

Fy = -51.3 N
