b) Figure 1 presents two plates held together by a stainless-steel bolt. The bolt is tensioned to +20 kN and subjected to a shearing force of +10 kN from the plates. The yield point for the stainless-steel material was measured in a uniaxial tensile test as 300 MPa. Using Plane Stress Theory, determine the minimum safe diameter (p) of the bolt using the Failure Theories proposed by W. Rankine and H. Tresca if the factor of safety of 2.5 is desired. [10] 20 kN ?
