Ask Mario, our electrical expert Marlo answers all your questions
Hi, MarlO. My name's Bob. How does the burglar alarm on my wi.- IOl:)(k?
Mario 's answer:
J_ --
Well, Bob, on your window there's a small magnet. Next to ot, on the window frame, there's a metal swllch and two terminals. The terminals are attached to two wires and the wires are connected to a battery and a buzzer. They make a simple circud. When the window os dosed, the SW>tch os next to the magnet. The magnet pulls the switch towarcls it. This doses the circud and electncity flows through tt. The buzzer does not sound.
·- - 5 8--
When the burglar opens the window, he breaks the circuit. The magnet moves away from the switch and this allows the spring to pull the switch back. This opens the circuit. The open circuit prevents the current from flowing. When this happens, the buzzer makes a sound.
But how does the buZzer sound wtlerl there tS no ClfCull?

6 Read the nexi part of the web page. Check your answer to 5.
Because there is another circuit. The buzzer has its own circuit. When the window circuit opens, this makes the buzzer circuit close.
How does this happen?
The buzzer circuit has its own battery, an electro· magnet and a relay switch. This is how it works: 1 The window circuit opens. 2 This causes the electro-magnet in the window
circuit to switch off. 3 The electro-magnet releases the relay switch
on the buzzer circuit. This allows the spring to push the switch. The buzzer circuit closes.
4 The current flows from the battery around the
The buzzer circuit
buzzer circuit. This makes the buzzer produce a loud noise.
OK, I understand the circuit. But how does the buzzer make a sound?
That's easy. Here's what happens: 1 The current flows through the buzzer circuit. 2 The current makes the electro-magnet switch on. 3 The electro-magnet pulls the metal strip away from the thin wire. 4 This causes the current to switch oft again. 5 When the current switches off. the electro-magnet switches off. 6 This allows the metal strip to spring back towards the thin wire. 7 The metal strip moves quiekly up and down. This makes the loud buzzing noise.
Thanks, Mario. I get it now.

The wind turbine consists of a tower, a rotor and a housing. The rotor oonsists oi three blades, and a hub.
The housing is a strong rigid container. It contains a lo\v·speed shaft. a high-speed shaft. two gears. a generator, a controller. and a brake.
The low-speed shaft connects the rotor to the gears. The highspeed shaft connects the gears to the generator.
Inside the housing, at the back, behind the generator, is the controller.

The Mars Science Laboratory. or MSL. is a rover. or mobile robot. II can move around on the surface of Mars.
Look at the diagram of the rover. II has a body. six wheels, two robot arms, two antennas and a mast. The antennas and lhe mast are mounted on the body, and the robot arms are attached to the front of the body.
There are special tools at the end of each robot arm. Soirui tools break p1eoes of rock. Other tools dig and collect samples of soil. Scientdc instruments on the rover then analyse the sod and rock powder.
The top of the mast is about 2.1 metres above the ground. The mast supports two
robo1 arms
special cameras. They are called the Mas1Cam and the ChemCam. The MaslCam (mast camera) is al the top of the mast II looks all around the rover The ChemCam (Chemistry camera) has a laser gun. The gun fires a laser beam at rocks up to 10 metres away and breaks them into powder. The camera then analyses the powder.
The rover is about 2.2 m long and its total mass is jusl under 800 kg. This includes at least 60 kg of scientific Instruments.
II has a six·wheel drive and a special suspension system. The wheels are made of titanium and are 25 cm in diameter. The suspension system allows the six wheels to remain on the ground all the 11me. II also allowS the rover 10 go over big rocks (up 10 75 cm high), and over deep holes. Each wheel has 11s own motor. This allows the vehicle 10 rotate 360 degrees. It can move at a speed of up to 90 metres per hour. The average speed is about 30 metres per hour.
The rover can operate in the temperature range on Mars. This ranges from - 120"C mi111mum up 10 as·c maximum.
The fOV'er can travel up to 200 metres per day and can operate for up 10 one Mars year (approximately 687 days).
