Suppose a heat engine is connected to two energy reservoirs, one apool of molten aluminum (660°C) and the other a block of solidmercury (-38.9°C). The engine runs by freezing 1.10 g of aluminum and melting 17.0 g of mercury during each cycle. The heat offusion of aluminum is 3.97 10^5 J/kg; the heat of fusion of mercury is 1.18 10^4. What is the effeciency of this engine?
The purpose of this project is to introduce you to the application of FEA by using the ANSYS software to examine the deflection of an I-beam under a point load.
