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.

Learners read an explanation of the RL time constant and examine the formula for calculating the instantaneous current value. The current is graphed as it climbs to maximum or drops to zero. Note* In the formulas in this module, the Greek letter epsilon should be the mathematical constant 'e'.

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