Please help with the following statics question:

The truss is made from five members, each having a length of 4m

mand a mass of 9kg/m (image below).

If the mass of the gusset plates at the joints and the thickness of the members can be neglected, determine the distanced to where the hoisting cable must be attached, so that the truss does not tip (rotate) when it is lifted.

Express your answer to three significant figures and include the appropriate units.
