An 10.2-kg stone at the end of a steel (Young's modulus 2.0 x 10^11 N/m2) wire is being whirled in a circle at a constant tangential speed of 11.6 m/s. The stone is moving on the surface of a frictionless horizontal table. The wire is 3.62 m long and has a radius of
4.10 x 10^-3m. Find the strain in the wire.

Explanation:

m = Mass of stone = 10.2 kg

v = Tangential velocity = 11.6 m/s

l = Length of wire = 3.62 m

r = Radius of wire =

A = Area of wire =

Y = Young's modulus of steel =

= Strain

The force acting on the stone will be centripetal

Stress is given by

Young's modulus is given by

Strain in the wire is .

i think it is non rem sleep
