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.
Learners apply lever ratios to calculate the mechanical advantage in basic mechanisms.
This interactive object is designed to help learners memorize the schematic symbols used in ladder logic diagrams. Learners quiz themselves using electronic flashcards.
In this interactive object, learners read an introduction to Class 1, Class 2, and Class 3 levers and then take a quiz.
In this animated and interactive object, learners examine the formula for horsepower and work practice problems.
In this animated object, learners examine the mechanical configuration of a three-way switch and how it operates in a circuit. They also view diagrams showing the use of an ohmmeter to determine the electrical connections.
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.
This animated lesson shows how to calculate the amount of force generated by hydraulic cylinders.
Learners read an analogy comparing an electrical transformer to mechanical gears.
In this animated object, learners examine formulas for displacement and velocity ratios. They also view examples and calculate velocity and the velocity ratio.
In this interactive object, learners match physiological, mechanical, or other parenteral nutrition complications with the appropriate nursing care.
Learners use trigonometry to calculate angular input forces involving Class 2 mechanical levers.
Learners solve two sample problems for a mechanical reasoning assessment.
