This will create an equal and opposite torque on the body. In addition, the performer can also correct sway by rotating the pole. This reduces angular acceleration, so a greater torque is required to rotate the performer over the wire. It distributes mass away from the pivot point, thereby increasing the moment of inertia. This technique provides several advantages. In both cases, whether side by side or parallel, the ankle is the pivot point.Ī wire-walker may use a pole for balance or may stretch out his arms perpendicular to his trunk in the manner of a pole. ![]() Therefore, a tightwire walker's sway is side to side, their lateral support having been drastically reduced. In the case of highwire-walkers, their feet are parallel with each other, one foot positioned in front of the other while on the wire. When they are on the ground with their feet side by side, the base of support is wide in the lateral direction but narrow in the sagittal (back-to-front) direction. shifting most of their weight over their legs, arms, or whatever part of their body they are using to hold them up. One solution is for the rope core to be made of steel cable, laid in the opposite direction to the outer layers, so that twisting forces balance each other out.Īcrobats maintain their balance by positioning their centre of mass directly over their base of support, i.e. Underfoot, this could be hazardous to disastrous in a tightrope. If the "lay" of the rope (the orientation of the constituent strands, the "twist" of a rope) is in one direction, the rope can twist on itself as it stretches and relaxes. A skywalk is performed outdoors between tall buildings, gorges, across waterfalls or other natural and man-made structures. Skywalk is a form of highwire which is performed at great heights and length. Although there is no official height when tightwire becomes highwire, generally a wire over 20 feet (6 m) high are regarded as a highwire act. Highwire is a form of tightwire walking but performed at much greater height. The technique to maintain balance is to keep the performer's centre of mass above their support point-usually their feet. ![]() Tightwire performers have even used wheelbarrows with passengers, ladders, and animals in their act. Object manipulation acts include a variety of props in their acts, such as clubs, rings, hats, or canes. Typically, tightwire performances either include dance or object manipulation. ![]() It can be done either using a balancing tool (umbrella, fan, balance pole, etc.) or "freehand", using only one's body to maintain balance. Tightwire is the skill of maintaining balance while walking along a tensioned wire between two points. Tightrope walking, Armenian manuscript, 1688
