The truss is made from five members, each having a length L and a mass density ρ.

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

Given:

L = 4 m

ρ = 7kg/m

L. L. 7, 60° 0° 0-0 60° (L/2) (cos 60°)

L. L. 7, 60 \60 0-0 60 (L/2) (cos 60)
