In this animated activity, learners examine the conversion of electrical energy into an electrostatic charge within the dielectric material of a capacitor.

In this animated object, learners examine the method of interpreting the truth tables for two-position and three-position selector switches on ladder logic circuit diagrams.

In this animated and interactive object, learners study how a DC circuit, consisting of a diac, a capacitor, and two resistors, causes a light-emitting diode to turn on and off. A brief quiz completes the activity.

In this interactive object, learners work 10 problems covering resistors, voltage, and current.

Learners examine the formulas for calculating work in ft-lb units and power in ft-lb/min. units. Practice problems are included.

Learners solve word problems involving basic mechanical principles such as torque, horsepower, work, and power. Students who have problems with a particular word problem may try it again with a different set of numbers.

In this animated and interactive object, learners calculate the maximum velocity of the work stroke and the return stroke.

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.
