A specimen of a 4340 steel alloy with a plane strain fracture toughness of 54.8 MPa1m (50 ksi1in.) is exposed to a stress of 1030 MPa (150,000 psi). Will this specimen experience fracture if the largest

The power source in a certain welding setup generates 3500w that is transferred to the low carbon steel work with a heat transfer factor of 0.85. the melting factor in the operation is 0.45. a continuous fillet weld is to be made with a cross-sectional area of 23 mm2 determine the travel speed at which the welding can be accomplished.
