Beam held up by two columns I apologize in advance if you think this should really go in the homework help area, I am not sure because this isn't a homework problem, but rather my struggle to understand and carry out concepts. If it needs to be re-posted, or moved, I understand. :) In a building a beam is held up by two columns, and only two columns. I need to show that the columns are strong enough to hold up the beam. I thought the best way to do this would be to find the safety factor, and by showing that this value was high enough I would know that it would work. Safety factor can by shown by, Ultimate load/actual load Or, Design load/ expected load I know the Tensile yield strength is 345 MPa (50 ksi) and tensile ultimate strength 450 MPa (65 ksi) of the column. The cross sectional area of the column I found to be, 8.109 in^2, which is also 0.20596 meters. It is an I beam that I calculated the cross sectional area for. How do I find out the force that the two columns can hold? That way I can use the safety factor with the load method. Or is that the wrong way to do it? Keep in mind, I am trying to find the safety factor, so I can't assume its anything to help me find other data.
