Question: A bolt is subjected to a variable stress that varies from 100 MPa to 200 MPa. The area of cross section of the bolt

A bolt is subjected to a variable stress that varies from 100

A bolt is subjected to a variable stress that varies from 100 MPa to 200 MPa. The area of cross section of the bolt is 100 mm and stiffness of the part held together by bolt is three times the stiffness of bolt. If the external load on the bolt varies from 0 to P (kN), the value of initial load on bolt is (kN)
