1.	Calculate the load stress if the value of force is 20 N and the area of cross-section is 2 m^2.(a) 10 N/m^2(b) 20 N/m^2(c) 30 N/m^2(d) 40 N/m^2I have been asked this question during an interview for a job.Question is from Motors Rating and Heating topic in division Rating and Heating of Motors of Electric Drives
Answer» The correct CHOICE is (a) 10 N/m^2 The best I can EXPLAIN: The STRESS is defined as the ratio of the internal RESTORING FORCE and area of the cross-section. Stress=Fres÷A=20÷2=10 N/m^2.
