Question

Three members DA, DB, and DC (could be cables or solid members) hold a 56-meter vertical post DE in place. The direction cosines of DC (measured from D) are -0.3503 and 0.2866 along.

Answer 1

The question asks about three members holding a vertical post in place, and we need to find the direction cosines of one of the members.

Step-by-step explanation:

The question is about three members (cables or solid members) that hold a 56-meter vertical post in place.

The given information includes the scalar components of one of the members.

To solve the problem, we need to use the given scalar components and find the direction cosines of DC measured from D.
