The disclosed system is directed towards a multi-hinge. The multi-hinge comprises a body including a first end and a second end opposite the first end. The first end defines a beam axis of rotation and the second end defines a bracket axis of rotation. A bracket coupling is rotatably coupled to the second end of the body along the bracket axis of rotation. The bracket coupling includes a rotary section rotatably coupled to the second end of the body along the bracket axis and a mounting section disposed coaxially with and rotatably coupled to the rotary section. The multi-hinge includes a base rotatably coupled to the first end of the body about the beam axis of rotation. The multi-hinge further includes a moment arm pivotally coupled to the base at a radial distance from the beam axis and pivotally coupled to the rotary section of the bracket coupling at the radial distance from the bracket axis. The multi-hinge includes a torsional preloading member coupled between the body and the base.
