After a brief review, the student solves five practical shop problems using right angle trigonometry.

In this interactive object, students view an animated depiction of Class 3 levers. A matching quiz completes the activity.

Learners review Ohm's Law and then work 12 problems. 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 animated and interactive object, learners examine the formula for horsepower and work practice problems.

Students complete 10 practice problems. These deal with the determination of series current, zener current, and load current, and if the zener diode is operating in the breakdown region.

The learner will identify ways to overcome barriers to critical thinking and problem-solving including false memories, personal biases and prejudices, and physical and emotional hindrances.

Decimals to Fractions

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

Learners examine the differences and similarities between hydraulic and pneumatic systems.

In this screencast, learners examine the construction of a 7493 IC as mod-2 and mod-8 up-counters. They view how this binary counter can be modified to operate at different modulus counts.

Learners read how to convert complex numbers to their polar equivalent in Excel.

Compare the behaviors and situations that interfere with effective communication in the workplace with those that enhance listening skills and career performance.

Learners listen to a workplace conversation and are tested on their retention of information. This activity has audio content.

In this animated and interactive object, the learner uses a TI-36X calculator to solve for the magnitude of the resultant and of one of the component forces in a right triangle.

In this animated activity, learners examine the operation of hydraulic directional control valves and the internal components that divert the fluid.

Learners view the operation of an NPN transistor in the active region.

In this animated object, learners examine how the way in which a rheostat is connected in series with other resistors causes current and voltage to change as the resistance is varied. A brief quiz completes the activity.

Learners compare electromagnetic quantities with the voltage, current, and resistance quantities of an electrical circuit. A brief quiz completes the object.

Learners read how inches of water column is used as a unit of pressure measurement. Practical applications and a conversion formula to psi are included.

In this animated activity, learners examine the three main segments of a hydraulic system: power supply, control, and output. A brief quiz completes the learning object.

Students review the best practices for using a ruler and answer five basic questions.

In this learning activity you'll test your ability to select the proper gage blocks when making a stack.

In this animated activity, learners observe how pressure values throughout a hydraulic system are developed based on pump pressure and the size of the load.

School or work stressing you out? Never feel like there are enough hours in the day? Improve your time management skills and get more time back for you.

Learners read how an inductor opposes a current change when it begins to energize and when it begins to de-energize. A short quiz completes the activity.
