a cFigure 2: Virtual lab components: a) the live script manual, b) the Simscape model, and c) theanimated visual model (for the controls labs only).DC Circuit Analysis Virtual LabsThere are six labs in the DC Circuit Analysis module: 1. Mesh Analysis 2. Nodal Analysis 3. Thevenin and Norton Equivalent Circuits 4. RC Circuits 5. RLC Circuits 6. Op AmpsThese topics were selected to match the first half of a typical circuits course. The labs do notreview AC circuits. However, the simulation tools can be applied to AC circuits with only minormodifications.In labs 1-3, students begin by writing the circuit equations on paper (Figure 3. a), and then solvefor

, meaningthe engine is cycled through the use of an electricmotor connected to the crankshaft. By maintaining aconstant engine speed and measuring the power Figure 10. Setup to measure mechanical efficiencydrawn by motor while removing key components(piston, camshaft, and valves), a difference in electrical load can be recorded and used tocalculate the difference in mechanical efficiency. The setup used a 4.5 hp engine donated byBriggs & Stratton for use in the ICE Laboratory, see Fig. 10. It was connected to an AC motor,which rotates at a speed of 1750 rpm and has 0.25 horsepower output which provides 9 in-lb. oftorque. The chosen 950 series Briggs & Stratton engine requires 50 in-lb. of torque to turnthrough the compression stroke
