A wire 4m long is stretched horizontally between points A and B 4m apart. A load W placed at the center of the wire produces a sag of 53.4mm, a. If the wire is 25mm2 in cross-section and the Young’s modulus is 200GPa, what is the magnitude of load W? b. If the load was reduced by 40%, what will be the sag?
