Unformatted text preview: yielding if the material is 18Ni maraging steel ( 1791MPa Y σ = )? Employ (a) Tresca and (b)Von Mises criterion. 9 . A simply supported beam has a solid cylindrical cross section. The beam is of length 1.0 m and it must carry a load of 1.0 kN uniformly distributed along its length. The beam must also support a torque of 1.0 kNm. The beam must have a safety factor of two against yield by the von Mises criterion. If the beam is made of AISI 4142 steel below, what is the mass of the beam? AISI 4142 (450°C Temper) steel: ρ = 7900 kgm-3 , σ y = 1584 MPa 10.
