Class 2 Levers: Force Input Angles
Learners use trigonometry to calculate angular input forces involving Class 2 mechanical levers.
Displacement and Velocity Ratios
In this animated object, learners examine formulas for displacement and velocity ratios. They also view examples and calculate velocity and the velocity ratio.
Mechanical Advantage (Screencast)
Learners apply lever ratios to calculate the mechanical advantage in basic mechanisms.
Identifying Lever Classes
In this interactive object, learners read an introduction to Class 1, Class 2, and Class 3 levers and then take a quiz.
Cellular Manufacturing
Learners read about the benefits of grouping machines together for an efficient flow of the product.
