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

Learners use trigonometry to calculate angular input forces involving Class 2 mechanical levers.

In this animated and interactive object, learners use rotational input velocity to determine the linear output velocity of a rocker or lever. Learners test their knowledge in an exercise at the end of the activity.

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