Question

desirable mechanical properties of an elevator cable

Answer 1

Elevator cable: The cable should not elon-gate elastically to a large extent or un-dergo yielding as the load is increased.These requirements thus call fora mate-rial with a high elastic modulus and yieldstress

Answer 2

For elevator we need high Toughness which is the ability of a material to withstand sudden loading or to absorb energy until it breaks and it is measuredin terms of modulus of toughness. And also Metal Fatigue which is the number of cycles for which a component or a specimen can endure an alternating loadmainly depends upon the magnitude or amplitude of that load.
