determined how piston displacement depends on crankangle in a single-cylinder internal combustion engine and compared their results to a theoreticalequation. A schematic of a piston, connecting rod and crank is shown in Figure 2. Assumingthat the crank and connecting rod have perfect pin connections, it can be shown by trigonometrythat the distance between the crank axis and the piston pin axis (s) is given by s = a cos + (L2 – a2 sin2 )1/2 (1)when the connecting rod length (L) and the crank radius (a) are known. These values, and thedistance from the piston pin axis to the top of the piston (x), are measured by the laboratoryinstructor and given to the students before lab. Figure 2

extensive use of pressure-enthalpy(P-h) diagrams that enable intuitive visualization of even the most complex steam power plantsto a high degree of accuracy. This is contrary to all current thermodynamic textbooks in whichtemperature-entropy (T-s) diagrams are used to represent steam power plants. This standardtextbook approach is non-intuitive in that there is no indication of the turbine power output, andincorrect in that the ideal feedwater pump process is always represented by a line when in fact itshould be closer to a single point.Another significant departure from traditional thermodynamic texts is the use of the ideal Stirlingcycle machine to represent the ideal reversible machine. The ideal Stirling cycle machine has athermal efficiency

and summarize the materials in a creative way to promote thestudents’ understanding. An appropriate assessment is for sure needed.1.1 Example 1There are many gas power cycles, such as Carnot cycle, Otto cycle and Diesel cycle. In mostcases, the textbook discusses each of them and shows the process in a P-v and/or a T-s diagram.The diagrams can help the student to understand and memorize these cycles. However, thestudents may become confused to remember these curves because all the curves are quite new tothem. To help the students in learning these cycles, it is seen that all the well-known reversiblecycles (Carnot, Ericsson and Stirling) can be integrated into one T-s diagram (or a P-v diagram).Figure 1 shows the individual diagrams of the

Some introductory physics textbooks17-20 skip the64 Clausius theorem altogether, and derive RHE efficiency starting from ∆S=0.

Returning to the purpose of this paper we can now surmise that it would be very usefulif, as we undertook our energy transfers, we could use a gage to quantify the degradationof energy ‘quality’ through our various processes or systems. A rapidly rising entropyreading would alert us to areas of high energy degradation and also allow us to comparedifferent processes more appropriately.Entropy. It turns out that there exists a property called Entropy which can be used as an indicatorof how the quality of energy is being degraded. This is the property our imaginary gagemust measure.

As students complete an activity, they are encouraged to refer to its correspondinggrading rubric, which conveys expectations of quality across different levels of expertise.
