As a mechanical engineer, you are required to suggest THREE suitable materials for cable elevator. The strength of the cable should more than 200 MPa and as tough as possible materials Index is listed as below: M = K_ic/sigma_f Choose the most suitable material to make the cheapest cable for elevator. (Use Appendices C & D for this question)
Solution
Answer
These cables can be made of
Carbon nanotubes
Kevlar (composite material)
Fibre reinforced composites (FRC)
Among them FRC are cheapest.
