Saya mau tau Strain gauge scale dari Dacin. Jelaskan dalam bahasa sunda

The deflection of a load-supporting béam can be méasured using strain gauge, which is a length-sensitive electrical resistance. The capacity of such devices is determined by the resistance of the béam to deflection and the results from several supporting locations may be added electronically and so this type of méasurement is especially suitable for determining the weight of very héavy objects, such as trucks and railcars, as is done in a modérn weigh bridge.
