this question is unanswerable without more information. Are you referring to a 4" steel stud? If so, it depends how closely the studs in the stud wall are spaced, how tall the studs are and if they have lateral bracing (and if so, how much/at what heights?). You also need to state what gauge the steel is. If you are referring to channel steel to be used as a beam/purlin/rafter - one would need to know the span and the thickness of the steel.
okay, simple fraction math:The two unknown sections of the beam, the 1/6 and 2/5, must be added together to find the fraction of the beam not above the water. LCD is 6x5=30. The result is 17/30. Subtract that result from one (the whole beam). 30/30 - 17/30 is 13/30. We now know that the 78' above the water is 13/30 of the whole beam.Proportion time: The whole beam has 30 parts. 13 parts of the beam is a length of 78'. A single part is 78/13 = 6'. Multiply 6' by 30 and you get 180', the length of the whole beam.Alternate Method: just set up the ratio and solve for x.13/30 = 78/x, 13x = 78*30, x = 78*30/13, x = 6*30, x' = 180'.
you can make a beam balance by putting a coloum in the centre of the beam
In order to compute the neutral axis of a beam, we need its dimension and shape.
It depends on what the beam is made of.
