Word Problems in Basic Mechanics
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.
Power Factor: A Mechanical Work Analogy
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.

Transformers - A Mechanical Gear Analogy
Hydraulic Mechanical Force
This animated lesson shows how to calculate the amount of force generated by hydraulic cylinders.
Quick-Return Mechanism Velocity Calculations
In this animated and interactive object, learners calculate the maximum velocity of the work stroke and the return stroke.
Converting Rotational Velocity to Linear Velocity (Screencast)
Students view an example of how to convert rotational velocity to linear velocity. They then work practice problems.
Critical Position
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.
SEO - Site Organization and Structure
In this activity, we will explain the mechanics of site structure and the role it plays in search engine optimization.
Torque Sequence of Two Mating Surfaces
In this interactive object, learners demonstrate the proper tightening sequence for mechanically joining two mating surfaces.
