Find the lightest W(12 or14) shape, A992 steel, to be used as a 30 ft column supporting a factored load of700 kips. Assume the column is pinned-pinned with restraints in the weak axis direction at the thirdpoints. Include the available compressive strength of the selected column and indicate whether this is dueto elastic or inelastic buckling.

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.

Different types of steels contain different elements that alter the characteristics of the steel. for each of the following elements, explain what the element does when alloyed with steel.

Inspection for bearing condition will include: (clo4) a)-color b)-smell c)-size d)-none of the above
