![In a tensile test on a metal specimen having a cross section 20 mm by 10 mm elastic breakdown
occurred at a load of 70 000 N.
A thin plate madec from the same material is to be subjected to loading such that at a certain
point in the plate the stresses are o,=-70 N/mm², 7.y= 60 N/mm² and o. Determine the
maximum allowable values of o, using the Tresca and von Mises theories of elastic breakdown.
