A vertical steel beam in a building supports a load of 7.2 104 N. (a) If the length of the beam is 4.0 m and its cross-sectional area is 7.1 10-3 m2, find the distance the beam is compressed along its length. (b) What maximum load in newtons could the steel beam support before failing? A cable used to lift heavy materials like steel I-beams must be strong enough to resist breaking even under a load of 1.3 106 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 9.0-m length of this cable stretch when subject to the 1.3 106-N load?
