5 kN 2. A steel bolt used in an assembly is subjected to a transverse shear force of 5 kN as shown in Fig.2. The yield strength of bolt material is 200 MPa and Poisson's ratio is 0.25. Assume factor of safety as 3. Determine the diameter of bolt using (i) Principal stress theory (ii) Max. strain theory (iii) Total Strain energy theory. Fig.2. Transverse shear load on bolt 5 kN Load
