Question

A weight of 1.0kg is suspended from the lower end of a wire of cross sectional 10 sq mm. Find the magnitude and direction of the stress produce in it .

Answer 1

Hey there!

Given,

Weight = 1.0 kg i.e Mass = 1 kg

Area = 10 mm² = 10^-5 m²

We know,

Force = mass * acceleration

         = 1 * 9.8

          = 9.8 N

And, we also know,

Stress = Force / Area

           = 9.8 / 10^-5

           = 9.8 * 10^5 Pa

Hence, Stress is produced of 9.8 * 10^5 Pa in vertically upward direction.
