Extracted text: 5kN Question 6 A mild steel bar 20mm x 20 mm in cross section is to be subjected to tension. Using a factor of safety of 4 based on the yield stress, find the working stress that is allowable in the steel bar. Hence, work out the allowable load. Given yield stress of mild steel is 250MN/m2.
