Automotive Electrical Systems: VAT-40 Starting System Test
In this highly interactive and animated object, learners examine the VAT-40 battery starting and charging system tester and study how the tester is used to diagnose vehicle starting system problems. This object has audio.
Learners take a close look at the Edison Wire System and observe how the current values through the two lines and the neutral of the system change as the loads vary.
In this animated activity, learners observe how pressure values throughout a hydraulic system are developed based on pump pressure and the size of the load.
Learners read an explanation of how the Magnetron Ignition System uses a solid state switching component, a step-up transformer, and magnetism to provide a high voltage spark in a one-cylinder combustion engine.
Learners play a vascular system "game" to identify the arteries, capillaries, and veins that make up the renal blood supply pathway. A score is given at the end of the activity.
In this interactive object, learners examine how work is performed in foot-pounds by a hydraulic system that uses a pump and cylinder. A brief quiz completes the activity.
In this animated object, learners examine the operation of a feed-forward control system and its advantages over a closed-loop system. A brief quiz completes the activity.
In this animated object, learners examine the operation of a closed-loop system that maintains the speed of a conveyer belt as heavy boxes are placed or removed.
Students read about the Federal Reserve System's structure and goals and the tools it uses to control the flow of money and credit in the economy. At the end of this activity, learners are asked to write how they would solve specific economic problems if they served on the Fed's Board of Governors.
