PASSAGE
A rigid L-shaped bracket is pinned to a wall at A and is also supported by a two-force link BC that connects pin B on the bracket to pin C on the wall. The bracket carries a load. An engineering student is checking whether member BC is in tension or compression by examining the direction of the force that BC exerts on pin B on the bracket.
The student finds that the force BC exerts on pin B of the bracket is directed from B toward C (i.e., along BC pointing away from the bracket toward the wall). Which of the following correctly interprets this finding?
