Falconry training and technique the jesses lying on the scale can change the reading, so the falconer has to be careful to lift them up while the bird is being weighed. Above that range of weight, the bird will be unresponsive in the field, lacking in motivation to hunt or return to the falconer in timely fashion. Gauntlets or gloves are used by the falconer to turn the arm into a suitable perching surface. Falconry gloves may only cover the fist and wrist, while gauntlets for larger species extend to the elbow. An eagle glove may cover the entire arm and a portion of
Space tether that scale). For some applications, the tensile force on the tether is projected to be less than 15 lbs (< 65 N) Material selection in this case depends on the purpose of the mission and design constraints. Electrodynamic tethers, such as the one used on TSS-1R, may use thin copper wires for high conductivity (see EDT). There are design equations for certain applications that may be used to aid designers in identifying typical quantities that drive material selection. Space elevator equations typically use a "characteristic length", L, which is also known as its "self-support length" and is the length of
