Hey, I am having difficulty with this question, thanks guys.

Two chain slings, one at each end, are used to support a rectangular box girder of mass 8 tonne. The length of each sling chain is 5m. The rectangular cross sectional shape of the box girder has dimensions of 1.5m by 0.5m

In part a of the equation it is lying width-side down (as to be longer horizontally) and each sling goes completely around the girder and reconnects with itself, to form a shape similar to this

/\

|_|

In part b however, it has been rolled over so the girder is taller (and less stable) than previously. Similar to:

/\

|_|

Im unsure how to calculate the tension, but i did find this (However it probably has no relevance to the answer at all);

the top section of the rope = 2.5m

hence each part is 1.25m long

yeah and um, that's it. quite pathetic really =\

is there a formula for calculating tension?

And if there is a formula for finding compression as well (in say, a brick lodged between two walls), could you say that too?

Thanks, Sam
