A steel cable with a radius of 1.5cm supports a chairlift at a ski area. If the maximum stress is not to exceed 10 8N/m2. What is the maximum load the cable can support?
7. A 6.0 m cylindrical steel beam 3.50 cm in diameter supports an overhead walkway.
The beam is designed to not stretch more than 5.0 x 10-5 m. What is the maximum load that the beam can withstand? If we assume an average mass of a person to be 75.0 kg, could the walkway support two people? Y steel = 20 x 101º N/m?
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?
