- C. Equally in all directions
- D. It is not transmitted through fluids
4. Why can a hydraulic system multiply a small input force into a larger output force?
- A. Because liquids are compressible
- B. Because pressure is the same throughout the liquid, so a larger piston area gives a larger force
- C. Because friction increases the force
- D. Because liquids are lighter than gases
