Introduction to selecting the proper punch and die for air bending or bottoming when forming on a press brake. Includes charts and methods for selection.

In this animated activity, learners examine the operation of normally open and normally closed valves used in hydraulics. A brief quiz completes the learning object.

In this screencast, learners examine the internal structure of an unloading valve. This learning object includes a video clip demonstrating the use of an unloading valve in a metal stamping application.

Students review the Current Divider Rule (CDR) and work practice problems.

In this interactive object, learners solve for total resistance and current, the current through each resistor, the voltage across each resistor, and the power dissipated by each resistor.

Learners work problems to make conversions between RMS, average, peak, and peak-to-peak AC voltages.

Learners review Ohm's Law and then work 12 problems to help them apply the law to automotive electrical systems. In each of the problems, students are given two of the three variables (voltage, resistance, or current) and are asked to solve for the third.

In this learning activity you'll practice solving for the total resistance of series-parallel DC circuits.

In this animated activity, learners examine the conversion of electrical energy into an electrostatic charge within the dielectric material of a capacitor.

In this interactive object, learners follow the steps required for the Ziegler-Nichols Continuous Cycling method. The process identification procedure is performed, calculations are made, and the proper PID values are programmed into the controller.

Learners view an animation of a counterbalance valve in operation and examine the valve’s internal structure.

In this animated and interactive object, learners follow steps that begin with choosing the correct drive roll and include feeding the electrode wire from the spool to the welding gun.

Learners use the National Electrical Code to determine the size of a motor overload protection device.

In this learning activity you'll understand what flow charts are and how they're used to create computer programs.

In this learning object, you’ll explore what tools should be a part of every welding tool bag.

In this animated object, learners examine the operation of a multiplexer and the function of the data input and selector lines. A brief quiz completes the activity.

Learners read how to calculate the MOD number and how it is used.

In this learning activity you'll practice using the 4-input truth table.

Learners view a demonstration showing that line-neutral voltages and line-line voltages are not in-phase with each other, but have a definite 30-degree relationship.

In this learning activity you'll identify the consequences of using gage blocks incorrectly.

This animated object allows students to examine the four steps used to reduce a complex circuit to a simple series circuit.

In this animated lesson, students view the operation of an electromechanical relay. A brief quiz concludes the activity.

Learners study the operation of a ladder circuit in which coils on one rung control contacts in other rungs.

In this animated activity, learners examine a systematic method for converting a decimal number (base 10) into a hexadecimal number (base 16).

In this animated and interactive object, learners follow two methods for converting a hexadecimal number to a decimal number. They test their knowledge in exercises at the end of the learning object.
