Astructural component is fabricated from an alloy that has a plane-strain fracture toughness of 62 mpa1m. it has been determined that this component fails at a stress of 250 mpa when the maximum length of a surface crack is 1.6 mm. what is the maximum allowable surface crack length (in mm) without fracture for this same component exposed to a stress of 250 mpa and made from another alloy with a plane-strain fracture toughness of 51 mpa1m?

Apump is used to circulate hot water in a home heating system. water enters the well-insulated pump operating at steady state at a rate of 0.42 gal/min. the inlet pressure and temperature are 14.7 lbf/in.2, and 180°f, respectively; at the exit the pressure is 60 lbf/in.2 the pump requires 1/15 hp of power input. water can be modeled as an incompressible substance with constant density of 60.58 lb/ft3 and constant specific heat of 1 btu/lb or. neglecting kinetic and potential energy effects, determine the temperature change, in °r, as the water flows through the pump.
