In this animated object, learners examine formulas for displacement and velocity ratios. They also view examples and calculate velocity and the velocity ratio.

Learners examine how a linear displacement transducer is used to measure the linear position of a physical object. Animations show the sequential steps of the entire operation.

Learners examine the operation of positive and non-positive displacement compressors used in pneumatic systems.

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.

In this animated object, learners examine how various types of positive and non-positive displacement hydraulic pumps work.
