Design a beam for a 26 ft simple span to support WD = 2 k/ft, WL = 3 k/ft and a concentrated load of PL = 20k at midspan. The beam is fully braced. The maximum permissible deflection is 1/1000 of the span. Use LFRD method and Fy = 50 ksi. Consider moment, shear, and deflection.

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.
