In this interactive learning object, students view the ammeter connections for measuring currents in a parallel circuit with three branches on an energy concepts lab board. A brief quiz completes the activity.

Learners are introduced to the maximum power transfer theorem. Examples show the load as it varies and the results are graphed.

Learners study the fundamental operation of a triac, particularly how it is turned on and off. A brief quiz completes the activity.

In this animated object, students view diagrams of the UJT as it is used in the relaxation oscillator circuit. Waveforms illustrate how the circuit operates through several time periods.

In this animated object, learners examine the situation that occurs when any two links of a mechanism lie in the same plane or on a straight line. Crank-sliders and crank-rockers are shown.

Picture of Adira hydraulic shear's operator's panel with part identification and instructions on how to start and stop the shear as well as setting stroke (cutting length).

Introduces two methods of determining bend allowance; one is simple and is an approximate, the other is more precise. Interactive part has learner calculate bend allowance and blank size.

The learner reads about safety considerations for operating a hydraulic metal shear. Text, graphics and a brief assessment are included.

In this learning activity you'll review safety considerations for persons using a hydraulic iron worker and takes a short quiz.

Answer questions about Distance and Displacement, Speed and Velocity, Acceleration, Forces, and Units of Measurement. Answer correctly and you'll get to play a candy crush type game, but with vegetables.
