The maximum stress that can be applied to the material of a wire used to suspend an elevator is

1.3 \times 10^8 \mathrm{~Nm}^{-2}

. If the mass of the elevator is

900 \mathrm{~kg}

and it moves up with an acceleration of

2.2 \mathrm{~ms}^{-2}

, what is the minimum diameter of the wire?

View answer and explanation

Correct option: A

1.0284 \times 10^{-{2}} \mathrm{~m}

Option A (

1.0284 \times 10^{-{2}} \mathrm{~m}

) is correct because it is the minimum diameter of the wire calculated based on the maximum stress, mass, and acceleration of the elevator.
