An aluminum alloy [e = 73 gpa] cylinder (2) is held snugly between a rigid plate and a foundation by two steel bolts (1) [e = 180 gpa]. the aluminum cylinder has a length of l2 = 275 mm and a cross-sectional area of 2300 mm2. each steel bolt has a length of l1 = 335 mm and a diameter of d1 = 14 mm. the bolt has a pitch of 1 mm. this means that each time the nut is turned one complete revolution, the nut advances 1 mm. the nut is hand-tightened on the bolt until all slack has been removed from the assembly but no stress has yet been induced. determine the magnitude of the normal stress produced in the aluminum cylinder when the nut is tightened one complete turn past the snug-tight condition.

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.
