Question

Calculate the radius of steel wire required to lift a mass of 10metric tones.
Given Young’s modulus of steel wire is 2x1011 pa. ​

Answer 1

Answer:

If Young's modulus for steel is 2.0×10

11

Nm

−2

, then how much weight be suspended from a steel wire of length 2.0m and diameter 1.0mm so that the length of the wire be increased by 1.0mm? (g=9.8ms

−2

)

The change in lengthl=

πr

2

Y

FL

where F is weight to be suspended , L=2.0 m is initial length of wire, and r is radius of wire= .5 mm with Y as Young's modulus of material

putting these values we get F=78.5Newton or mass as

9.8

78.5

The change in lengthl=

πr

2

Y

FL

=8.01kilogram
