Calculate the net longitudinal stress σc=20N/mm^2, σI=11N/mm^2 and μ=0.2(a) 6N/mm^2(b) 7N/mm^2(c) 8N/mm^2(d) 9N/mm^2The question was posed to me in an interview for internship.My enquiry is from IC Engine topic in section Design of IC Engine Components of Automotive Engine Design

Answer» RIGHT OPTION is (a) 6N/mm^2

Easy EXPLANATION: (σI)net=σI-μσc

=11-0.2×20

=7N/mm^2
