## Two forces P1=15 kN and P2=18 kN are applied as shown to the end A of bar AB, which is welded to a cylindrical member BD of radius c 20 mm.

Knowing that the distance from A to the axis of the member BD is a 50 mm, and assuming that all stresses remain below the proportional limit of the material, determine the norma and shear stresses at point K located at a distance b 60 mm from end B.

## Water is the working fluid in a regenerative Rankine cycle with one closed feed water heater.

Water is the working fluid in a regenerative Rankine cycle with one closed feedwater heater. Steam enters the turbine at 1400 lbf/in. and 1000°F and expands to 120 lbf/in. , where some of the steam is extracted and diverted to the closed feedwater heater. The remaining steam expands through the second-stage turbine to the condenser pressure of 3.5 lbf/in. Each turbine stage and the pump have isentropic efficiencies of 80%. Flow through the condenser, closed feedwater heater, and steam generator is at constant pressure. Condensate exiting the feedwater heater as saturated liquid at 120 lbf/in. undergoes a throttling process as it passes through a trap into the condenser. The feedwater leaves the heater at 1400 lbf/in. and a temperature equal to the saturation temperature at 120 lbf/in. The net power output of the cycle is 1 x 10 Btu/h. Determine for the cycle: (a) the mass flow rate of steam…
