A beam of negligible mass of length 3 m is suspended by a string attached to a wall such that the angle between beam and string is 30 degree, and the beam is held horizontal with a sky weight. Find the tension in the string? Find the compression force on its beam? Thanks...

If the beam has no mass, the beam will not fall if the string is cut. So the tension of the string must be...
What does "sky weight" mean? That is a term I have never heard in my engineering lifetims.
