Hi folks, I'm a construction worker helping to destruct an oil platform out in the north sea, I often have to work out weights applied on lifting slings during cross hauling scenarios like the one drawn here, I know 2 ways of working this out already; 1 using a calculation of all the triangles lengths and another by drawing a triangle having one side representing the load ie,1000kg = 10 cm and then drawing the rigging angle side which should represent the tension... however, I'm sure there's a way of calculating this using the angles, cos and sin ... I've had a play but can't get my head round it, can anyone help me with this by explaining the equation please? ps I am not all the best with mathematical symbols so if you could explain it as I would enter it into the calculator id appreciate it, Thanks Ted
