The document discusses communicating vessels and hydraulic presses. Communicating vessels are devices where two or more vessels are connected by a tube, causing them to equalize in water level. Hydraulic presses work similarly, multiplying force through transmission of pressure in a fluid. Examples given include how car brakes and fork lifts function through hydraulic systems to produce larger forces from smaller inputs.

Communicating vessels 1.- Definition 2.- Exercises Exercise 1 Exercise 2 Exercise 3 Hydraulic press 1.- Definition 2.- Exercises Exercise 1 Exercise 2 Exercise 3
Communicating vessels are devices where two o more vessels with the same or different shapes are communicated at the bottom by another tube.
Exercise 1 Where are water reservoirs located in a village, at the same, lower or higher lever that houses are Why? http://www.galleryof3d.com/site/gal-profile.php?ID=7
Answer At a higher level, because as higher the level is higher is the pressure. http://www.bhassoc.com/sec_ww/ww_water_storage.htm
Exercise 2 Why is there the same level of water in the toilet? http://www.commerce.com.tw/products/EN/T/Toilet_Water.htm
Answer Because it has the level of the higher point of the pipe, as we have seen on the explanation of communicating vessels.
Exercise 3 When do you think the flowers stop being watering? http://www.rittenhouse.ca/asp/product.asp?PG=1016
Answer When the level of the water in the container is at the height of the end of the hose.
A hydraulic press is a force multiplier. It is a device similar to communicating vessels. It produce a large force from a small one
Exercise 1 Explain how the car brakes work
Answer When a force acts on the brake pedal, the pressure is transmitted through the fluid in the pipes and forces the liquid in the pipes against the brake drums on the four wheels
Exercise 2 Which force is smaller, force in or force out? Explain why
Answer Force in is smaller because the surface of its piston is smaller.
Exercise 3 Explain how a fork lift works
Answer When a force acts on the control lever, the pressure is transmitted through the fluid that makes the fork lift up.
