## Hydraulic Advantage

Source: Wikimedia

**Type:** Mini-lesson

**Theme:** Geometry

**Grades:** 6, 7, 8, 9, 10, 11, 12

**Learning Target:** Students will calculate the mechanical advantage of a hydraulic lift system using area, volume, and the pressure equation.

Instructions

The math learning targets are:

- Students will calculating volume of a cylinder (Slides 2, 5, 6)
- Students will use ratios to solve for unknowns (Slides 8, 9, 10)

(cross-multiplication is OK)

The physics learning target is:

- Students will calculate the change in volume to learn that in a closed hydraulic system, volume of the liquid does not change and does not compress (Pascal's principle).
