To manufacture a piston with a circular cross section, an alloy steel bar is required whose length is fixed and has a value of 35 cm and must withstand a compression load of 5.2 tons. For its design, a safety factor of 4/5 is suggested with respect to the yield stress. The shear modulus for that alloy is 80 GPa.To know the resistance of this steel alloy, a compression test was carried out on a specimen of the same material, from this test the data table of stress against engineering deformation shown was obtained.
