Learners examine the internal components of an optical encoder used in automated manufacturing applications. A brief quiz completes the animated activity.

In this interactive object, learners examine sectional views used in engineering drawings. The sections shown are full, half, offset, aligned, revolved, and broken-out. Learners match drawings of sectional views with the names of the views.

In this interactive object, learners determine the Vp, Vp-p, Vrms, Vavg, and the frequency of a sine wave that is displayed on an oscilloscope screen.

Learners solve six problems determining the total capacitance of a parallel circuit. Immediate feedback is provided.

Learners follow the steps required to perform the Ziegler-Nichols reaction curve process identification procedure.

Learners study the mathematical calculations used to determine the proper PID values to be entered into a controller using the Ziegler-Nichols Reaction Curve.

Learners examine an animated motion-controlled robotic arm and observe the operation of a PID (Proportional-Integral-Derivative) control that makes movements quickly without overshooting or having a steady-state error. This activity has audio content.

The learner calculates the resultant of multiple forces acting in a concurrent, coplanar load condition.

In this simulation, learners follow a series of steps to operate the Marvel Saw PCII in the manual mode. This activity includes a video clip.
