NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. A store sign is hung by two cables from post AB. The post is hinged at A and is supported by cable BC. It is desired to determine all forces acting on post AB by applying equilibrium to post AB. The tension in cable DE is 214 N, and the tension in cable FH is 155 N. 2.5 m 0.75 m E OPEN -0.6 1.5 m 0.4 m B F H What is the magnitude of the force by cable BC on post AB at B, TBC? The magnitude of the force by cable BC on post AB at B, TBC is N.
