Learners solve two sample problems for a mechanical reasoning assessment.

Learners apply lever ratios to calculate the mechanical advantage in basic mechanisms.

This animated lesson shows how to calculate the amount of force generated by hydraulic cylinders.

Learners read an analogy comparing mechanical work (in this case, sliding a weight) to that of electrical power. The relationship of work, apparent work, and power factor is developed.

Learners read an analogy comparing an electrical transformer to mechanical gears.

Learners solve word problems involving basic mechanical principles such as torque, horsepower, work, and power. Students who have problems with a particular word problem may try it again with a different set of numbers.

In this interactive object, learners are given the RPM, the pulley diameter, and the force, and proceed to calculate belt velocity and horsepower.

In this simulation activity, an electrician troubleshoots a defective water pump that will not start. To find the problem, the learner selects the appropriate blueprints that must be referred to while performing the troubleshooting steps. Then safety protocols will be followed, such as making lockout-tag out installations and donning PPE items before taking measurements with a multimeter to locate the faulty component.

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

This interactive object is designed to help learners memorize the schematic symbols used in ladder logic diagrams. Learners quiz themselves using electronic flashcards.

Learners examine the formulas for calculating work in ft-lb units and power in ft-lb/min. units.

This activity is a simulation that allows the learner to practice personal protective equipment tasks.

In this simulation activity, an electrician will troubleshoot an AC motor that is overheating. Before accessing blueprints and then using a multimeter to find the fault, the learner will follow safety protocols by following lock-out tag-out procedures and then suit up with appropriate (PPE) personal protection equipment.

In this simulation activity, an electrician troubleshoots a defective compressor motor that will not start. To find the problem, the learner selects the appropriate blueprints that must be referred to while performing the troubleshooting steps. Then safety protocols will be followed, such as making lockout-tag out installations and donning PPE items before taking measurements with a multimeter to locate the faulty component.

In this interactive object, students view an animated depiction of Class 1 levers. A matching quiz completes the activity.

Students view an example of how to convert rotational velocity to linear velocity. They then work practice problems.

In this animated and interactive object, learners examine the formula for horsepower and work practice problems.

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

In this animated and interactive object, learners calculate the maximum velocity of the work stroke and the return stroke.

In this interactive object, learners read an introduction to Class 1, Class 2, and Class 3 levers and then take a quiz.
