In this animated object, learners see how a time proportioning operational amplifier varies an average DC voltage. A brief quiz completes the activity.

In this animated activity, learners examine how cavitation occurs in a hydraulic pump. A video clip is included. Learners then test their knowledge in a brief quiz.

In this animated object, learners observe the operation of a J thermocouple with a cold junction. A table is used to convert the voltage it produces to a corresponding temperature. A brief quiz completes the activity.

Learners read what the letters DMAIC stand for and then complete a matching activity.

In this learning activity you'll apply the Pythagorean Theorem to isosceles and equilateral triangles.

Learners apply the Law of Cosines to determine forces using a TI-36X calculator in this animated object.

In this interactive and animated object, learners apply the Law of Cosines to determine forces using a TI-86 calculator.

In this interactive learning object, students calculate a resultant of multiple forces acting in a concurrent, coplanar condition.

The learner calculates the resultant of multiple forces acting in a concurrent, coplanar load condition.
