Estimate the maximum bending force requires for a 3 mm thick and 300 mm long Ti-6Al-4V titanium alloy sheet (Sy=925 MPa, S_UT = 1000 MPa, and E=110 GPa), annealed and quenched at 25 oC, in a wiping die with a width of 150 mm. Hint: recall that k-factor for a wiping die varies from 0.3-0.34. A)5.3 kN B)5.7 kN C)633 kN D)None of the above

For a large plate, the geometry factor, f, is 1.03. Suppose a steel casting alloy has a critical fracture toughness of 78,886 psi*in1/2. The steel will be exposed to a stress of 40,295 psi during service. Calculate the minimum size of an edge crack that will grow. Repeat the calculation for Al2O3 with a fracture toughness of 1,600 psi*in1/2. How many times larger is the minimum size edge crack in the steel versus the alumina?

Which curve shown below (A or B) is for a BCC metal and why? A В Brittle + More Ductile Temperature Duclile-o-britte transilion temperalure Impact Energy

Determine the material property of the materials from the following website. Material Property Data (www.matweb.com) Material: Carbon Steel C1045 (AISI 1045) Cold Drawn - 1 in. round Property: %Elongation at Break (%) 12

List 3 of the design methods that can be applied to avoid the occurrence of fatigue

An ordinary mild steel bar has been prestressed to a working stress of 200 MPa. If the Young's modulus of steel is 200 GPa and permanent negative strain due to shrinkage and creep is 0.0008, what is the effective stress left in the steel?
