Learners apply lever ratios to calculate the mechanical advantage in basic mechanisms.

Learners solve two sample problems for a mechanical reasoning assessment.

Learners read an analogy comparing mechanical work (in this case, sliding a weight) to that of electrical power. The relationship of work, apparent work, and power factor is developed.

Learners read an analogy comparing an electrical transformer to mechanical gears.

In this simulation activity, procedures are performed to properly align the shaft of an electric motor that replaced a defective motor, with the shaft coupling of a pump to which it is attached.

Learners view an animated explanation of why an adjustment of the output voltage by an AC drive is required to maintain a constant torque as the frequency is varied.

This animated lesson shows how to calculate the amount of force generated by hydraulic cylinders.

In this animated and interactive object, learners examine the formula for horsepower and work practice problems.

In this interactive object, learners are given the RPM, the pulley diameter, and the force, and proceed to calculate belt velocity and horsepower.

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.

Datum precedence is a fundamental principle in the design and manufacture of mechanical parts and assemblies.

It refers to the order of importance assigned to different datums, which are specific points, lines, or planes on a part, which are used as references for measurement and geometric tolerances.

In this screencast, learners follow steps to determine the proper starting belt length for a timing, flat, or v-belt drive.

Learners use trigonometry to calculate angular input forces involving Class 2 mechanical levers.

In this interactive object, learners view various components of gears and read descriptions of them. Learners then identify the location of each of these components in a drag-and-drop exercise.

In this interactive object, learners match physiological, mechanical, or other parenteral nutrition complications with the appropriate nursing care.

In this animated object, learners examine the mechanical configuration of a three-way switch and how it operates in a circuit. They also view diagrams showing the use of an ohmmeter to determine the electrical connections.

In this screencast, learners examine the concept of gear ratios. The number of teeth, diameters, and velocity relationships are discussed and calculated using linear ratio equations.

This interactive object is designed to help learners memorize the schematic symbols used in ladder logic diagrams. Learners quiz themselves using electronic flashcards.

In this simulation activity, an electrician troubleshoots a defective water pump that will not start. To find the problem, the learner selects the appropriate blueprints that must be referred to while performing the troubleshooting steps. Then safety protocols will be followed, such as making lockout-tag out installations and donning PPE items before taking measurements with a multimeter to locate the faulty component.

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