Question

You have been asked to design a cable car to be used for lifting people to the top of a building. The cable is made of steel of diameter 12 mm and has a length of 24 m (6 floors). The elastic modulus and yield strength of the steel are 210 GPa and 250 MPa, respectively. If the lift car weighs 24,500 N, compute, The extension in the cable due to the weight of the car. The maximum number of people that can get into the lift without plastic deformation of the cable. Assume one person weighs 65 kg. Explain the assumption you have made to achieve your final result.

Explanation / Answer

For second problem u must have forgotten to consider car weight Eqn wud be like. Yield stress = ( 24500 + n . 65 . 9.8)/ area So n=5.92 So 5 people can accommodate
