Water is the working fluid in an ideal Rankine cycle. Superheated vapor enters the turbine at 10 MPa, 4800C, and the condenser pressure is 6 kPa. Determine for the cycle:
What are the two main categories of printed circuit board assemblies, as distinguished by the method of attaching components to the board?
a simply supported aluminum beam is found to deflect 0.4 in. at location a when a force of 2001b is applied at b. what

the combustion products in an internal combustion engine undergo an expansion process from an initial volume of 0.007
Two charged particles are initially separated by a distance d and the magnitude of the electric force on one is F1. If the distance is doubled, and the magnitude of the force on one of the particles is now F2, what is the ratio of F2/F1?
Also, derive an approximate expression for the strength-toweight ratio of the tube in terms of the working stress, its radius, and length L, and its specific weight ρg. This result is widely used in aircraft design.
Calculate the number of vacancies per cubic meter in some metal at 753°C. The energy for vacancy formation is 0.81 eV/atom, while the density and atomic weight for this metal are 6.38 g/cm3 and 49.43 g/mol, respectively. Find in m^-3 units.
By expanding Krel/Kcl in powers of v2/c2, estimate the value of v2/c2 for which Krel differs from Kcl by 10 percent.
Calculate the air outlet temperature and the heat removed from the vane - Generate a plot of the air outlet temperature as a function of flow rate for 0.1 m 0.6 kg/h.
For unstrained material, a = 2.8610. Find the values of the residual stresses parallel and perpendicular to the weld. Assume E = 30 × 106 psi, υ = 0.29, and that the stress normal to the plate is zero.
Consider an aluminum single crystal that has been stretched in tension applied parallel to x = [100] (σ x = +250 kPa) and compressed parallel to y = [010] (σ y = -50 kPa), with σ z = 0, where z = [001]. Assume that slip occurred on the (111) in the..
