An elevator of gross weight of 2,640 lbs hangs on a steel cable. The building code requires a safety factor of 12 for such a cable. (The weakest point of the cable should not break when loaded with 12 times the maximal operational load. Include units in your answers. More information. The weight of the cable itself can be neglected.) (a) What should be the smallest diameter of the required cable? 0.011161497 m x (b) What should be the smallest diameter of the cable if the elevator accelerates upwards with an acceleration of 0.5g?
