Question

Determine the stress in a solid steel rod of diameter 30 mm when subjected to a tensile load of 91 KN (your answer must be in MPa to 2 decimal places).
1 pascal = 1 N/m²
1 MPa = 10^6 Pa
Stress = Force /area, all in appropriate units.
= 91*10^3 N / (π0.030²/4) m²

Evaluate and convert to MPa.
