2 days ago · For more about construction, Ancient Wonders by Iris Volant and Avalon Nuovo is not primarily a book about how things work, but is nevertheless an excellent information book for 8-12 year olds on ancient technology. Readers learn about how the builders of ancient structures ingeniously manoeuvred massive slabs of stone using levers, pulleys and cranes, and how bronze sculptures were cast.
When Brenda's bakery burns down, the highly inefficient fire brigade floods the island, and the Inventor helps the islanders build a proper water pump. Topics covered: pumping, water pressure, air molecules.

Solids are just the opposite.If you've ever tried squeezing a block of metal or a lump ofwood, with nothing but your fingers,you'll know it's pretty much impossible. But what about liquids?Where do they fit in? You probably know that liquids are anin-between state, a bit l...
Turn a water pistol on its end and this is(crudely simplified) what's going on inside: Photo: A simplified view of a hydraulic waterpistol. When you press on the trigger (shown in red), you apply a relativelylarge force that moves the trigger a short distance. Because the water won'tsqueeze into a smaller space, it gets forced through the body of t...
You can see hydraulics at work in this digger.When the driver pulls a handle, the digger's engine pumpsfluid intothe narrow pipes and cables (shown in blue), forcing the hydraulic rams (shownin red) to extend. The rams look a bit like bicycle pumps working inreverse. If you put several rams together, you can make a digger'sarm extend and move much ...
How do hydraulic parts work together? Just like the components (parts) in something electric or electronic, they're connected into circuits. Instead of electrons whizzing around, there's hydraulic fluid flowing instead.A hydraulic circuit contains (at a minimum) something that supplies hydraulic power (a tank of fluid and apump—similar to the batte...
Not all hydraulic machines are so obvious, however; sometimes their hydraulic rams are hidden out of sight. Elevators("lifts") keep their workings well hidden, so it's not always apparent whether they're working in the traditional way (pulled up and down by a cable attached to a motor) or using hydraulics instead. Smaller elevators often use simple...
