Solar thermal heats water directly from the sun in panels called solar collectors. Fluid is pumped though the collectors and gets up to about 200 degrees F. That heat is then transferred to a storage tank, either directly in warm climates or through a heat exchanger in climates that freeze, as the hot fluid can be mixed with non-toxic antifreeze. For domestic hot water, that's about it, you just use the hot water in the tank for your showers and washing. For heating the house, you can either use the hot water for radiant floors, convection fan heaters, or forced hot air through a water to air heat exchanger.
The electric motor
Common elements are electric energy, water, vehicles, computers, workers, diversified types of machines, electronic devices, illumination, small mechanical devices and so on.
Sound waves are transformed into mechanical energy to make recordings by the use of a phonograph. The earliest recording devices of this type were hollow cylinders with tiny holes in them.
there is an instrument called lux meter. i believe that it works with a complex electronics circuitry using light sensitive devices. it directly gives the reading in lux.
an automatic safety brake is activated by the lack of electricity applied to a magnet or solenoid, these mechanical devices apply the brake when power fails. the brake is held open / off when electricity is on
no, False
It uses a complex system of magnets and other mechanical devices.
Mechanical devices mostly symbolize the parts, joints, rigid structures in it... they mostly symbilize the tough mechanical components therefore call as mechanical :)
Bearings are like invisible heroes inside mechanical devices because they make such mechanical devices to move right from their internal positions.
Electronics Devices are those devices which are made from semiconductors like transistors fet mosfet amplifiers and ic's and other p-n junction devices. while mechanical devices are those devices which follow the mechanical principle such as strain gauge , machines and robot etc.
Sound energy is mechanical energy. No devices are required to make a conversion.
A lever is a mechanical device.
mechanical engergy
radiant
IT is a study about mechanical devices which is AWESOME
They break and you die.
Mechanical Engineering has a good scope than ece....ece is all about electric devices and communication devices.......even mechanical engineer can do some of that job....mechanical can go in any field even in IT field if you are good at CAD....so i vote for mechanical......
