Question

A structural steel rod has a radius of 10mm and a length of 1.0m. A 150 KN force stretches it along its length. Calculate. (i) Stress (ii) Elongation and (iii) Strain on the rod Young’s modulus of structural steel is 2.0 x 10^11 Nm^-2

pls answer it fast ​

Answer 1

Answer:

option 2 elongation is the right answer

Answer 2

Answer:

option 3 is correct because in this l is given radius and force also and to find Young's modulus F/A*L/deltal
