3.) The diagram below shows a 5.5m long double angle brace which is connected by
6mm welding connection. The length of weld shown in the picture is 300 mm on the
top and 100 mm on the bottom. The 2-L127x 89x6.4 are 300W steel and long leg
back-to-back. The braces are to be welded to a 12 mm 350W steel gusset plate.
Determine the factored tensile capacity of the angles. Any intermediate connections
that are required should also be specified.
