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.

Students read an explanation of reactive power in a power distribution system involving motors, generators and transformers. A brief quiz completes the activity.

Learners view the steps to find the complex conjugate of a number in polar form using a TI-86 calculator.

Learners examine the symbols and values that control surface roughness, waviness, and lay. A brief quiz completes the object.

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.

Learners view a horizontal curve and mouse over the diagram to read descriptions of its components and related equations.

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