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

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

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.

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