Beams are important design elements in mechanical engineering and building construction that can deform under load. In linearelastic material behaviour, the bending line, also known as elastic line, is used to determine the deflection of beams. Deflection can be determined at any point on the beam using the influence coefficients and commutative theory. Beams are subjected to load transversely in the axial direction, which leads to deflection.
Features:
Beams of different materials: steel, brass and aluminium.
Learning Objectives And Experiments:
Elastic line and support forces in statically indeterminate systems.
Elastic line under varying load.
Elastic line under various support conditions.
The process of Dropwise Condensation is enhanced by the special water cooled condenser surface finish that prevents wetting of the surface. This continuous cleaning puts the water cooled surface in direct contact with the vapour. Condensation then occurs in droplets which grow and fall under gravity. These falling droplets wipe the surface clean ready for more droplets to form.
Vapour may condense onto a cooled surface in two distinct modes known as Filmwise and Dropwise. However it involves special surface finishes or treatment in order to maintain Dropwise Condensation and for this reason, though desirable, it seldom occurs in real plant operation. For the same temperature difference between the vapour and the surface, Dropwise Condensation is several more times effective than filmwise.
The film effectively acts as a resistance to heat transfer, as heat must be conducted through this film to the internal cooling water. The duplicate Filmwise Condenser is not specially treated and allows condensation to form as a film. This effectively grows and runs down the condenser gaining thickness as it falls.
The engine can be operated as an external ignition petrol engine or an auto-ignition diesel engine. The mode of operation can be changed by a few simple conversion steps. This allows the compression ratio to be adjusted over a wide range. The key feature is that the cylinder has been modified so that its height can be adjusted along with that of the cylinder head. Major technical modifications have been made to a standard water-cooled single cylinder engine to allow demanding issues in engine technology to be investigated by experiment.
Learning Objectives/Experiments:
Influence of ignition point on fuel consumption, power output, efficiency and exhaust gas composition
Comparison of diesel and petrol cycles
Plotting of torque and power curves
Determination of volumetric efficiency and lambda (fuel-air ratio)
Energy balances
Determination of friction loss (in passive mode)

The simulator takes into consideration all the devices, circuits and systems for the starting and the recharging. The combustion engines must be started with a special device because, differently iron the electric motors or the steam engines, they cannot start by themselves. The simulator analyzes in detail all the different phases relevant to the starting transistors, the conditions of standard operation, the recharging and the situations or variation of the electric loads.
In particular the following components are analyzed:
Alternator
Connecting circuits
Battery
Starter.
