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

This project gives a drawing with steps to complete the activity.

In this animated object, learners examine how the rotation of an induction AC motor's armature slips behind the synchronous rotational speed of the stator's field to create magnetic fields. These fields interact and produce torque. A quiz completes the activity.

In this animated activity, learners examine how various NAND gate configurations and the logic signals produced throughout the circuit perform the functions of all of the other types of logic gates.

In this animated and interactive object, learners examine a depiction of how force is multiplied by a larger cylinder when pressure from a pump is applied to a smaller cylinder. A short quiz completes the activity.

Learners examine how the load resistance connected to the secondary coil of a transformer affects the primary current. A brief quiz completes the activity.

In this interactive and animated object, learners examine the construction of a 7493 IC as mod-2 and mod-8 up-counters. They view how this binary counter can be modified to operate at different modulus counts. A quiz completes the activity.

Learners read how to set up a TI-86 calculator. The process is demonstrated and examples are given.

The learner examines the setup process of a TI-83 Plus calculator. The process is demonstrated and examples are given.
