A cable used to lift heavy materials like steel I-beams must be strong enough to resist breaking even under a load of 1.7 106 N. For safety, the cable must support twice that load. (a) What cross-sectional area should the cable have if it's to be made of steel? (b) By how much will a 7.0-m length of this cable stretch when subject to the 1.7 106-N load?
