In this animated object, the learner examines 17 types of joint movement.

Students analyze the eight single variable Boolean theorems and their expressions.

In this learning activity you'll practice calculating a joint variation problem.

In this animated object, learners examine the different types of joints and their movements.

The learner will gain an understanding of the modes of axis movement for successful robot programming.

In this animated lesson, the learner examines how a ladder circuit causes the cylinder of a hydraulic circuit to make a single extension and retraction.

Learners will understand how the interaction of the armature magnetic field and the rotating stator field cause the rotor of a single-phase AC motor to turn.

In this interactive object, learners review the major parts of the skeletal system by clicking on the correct term as each bone or joint is highlighted on a skeleton.

Learners follow steps to size a sanitary sump using the Wisconsin Plumbing Code. A quiz completes the activity.

Students follow the steps that are required to select a transformer with the proper ratings. Voltage, frequency, current, and KVA are considered.

In this animated and interactive object, the learner designs a treatment plan that includes precautions and adaptive equipment.

Learners follow the steps for reducing all of the elements of a complex circuit to a single current source and a single source resistance to create a simple circuit. Several examples are given for dc circuits. The conversion between Thevenin and Norton is also presented.

The learner will understand the two methods used to create a phase shift in current between two windings.

Students look at the power dissipated by a single gate and by an IC. The concept of average current draw is introduced and examples are provided.

Learners study the muscles of the scapula and check their knowledge on each page by identifying the muscles on diagrams and answering a related question about movement.

In this animated and interactive object, learners examine the basic parts and the linear movement of a hydraulic cylinder. A brief quiz completes the activity.

In this learning object you'll review direct, inverse, joint, quadratic, and combined variations.

In this animated object, learners consider how nanoscientists are mimicking intracellular movements when building nanobots.

Learners solve for voltage, current, and power in a single source, six-resistor circuit. A help screen is provided.

Learners examine four stages of rheumatoid arthritis and compare them to the normal synovial joint.
