Question

a structural steel rod has radius of 9.5 mm and length 81cm A force=6.2×10⁴ N streches its along length find stress of rod​

Answer 1

Answer:

218.672mpa

Explanation:

stress is simply defined as the resisting Force acting per unit area,

stress = Force / area of cross section,

Therefore,

stress induced along its length,

= (6.2*10^4)/(π*(9.5)*(9.5)) N/mm^2

= 218.672 mpa
