Explanation:
spring force frictonal
10880N
We are given that
Mass of elevator, m=850 kg
Acceleration,
We have to find the tension in the cable.
We know that
When elevator is accelerating upward then tension in the cable
Using the formula
density=mass/volume
mass=67.5
volume=15cm cube
so
67.5/15
4.5g/cm cube
