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.

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 read an analogy comparing an electrical transformer to mechanical gears.

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

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.

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

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

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

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

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.

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

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

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 interactive object, learners demonstrate the proper tightening sequence for mechanically joining two mating surfaces.

In this interactive object, learners read an introduction to Class 1, Class 2, and Class 3 levers and then take a quiz.

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