The three forces acting on the block each have a magnitude { F }_{ 1 } = { F }_{ 2 } = { F }_{ 3 }. Replace this system by a wrench and specify the point where the wrench intersects the z axis, measured from point O.
Given:
{ F }_{ 1 } = 10 Ib\quad a = 6 ft
{ F }_{ 2 } = { F }_{ 1 }\quad\quad b = 6 ft
{ F }_{ 3 } = { F }_{ 1 }\quad\quad c = 2 ft
