How do mechanical toys work?
Mechanical toys work by using a variety of electronic based on their intended function. Most use batteries though some now use solar power.
What countries use mechanical energy?
All people use mechanical energy.
Use mechanical energy in a sentence?
The combination of rotational force and forward movement make it possible for the screwdriver to use mechanical advantage
How do you convert heat energy to mechanical?
In some refrigeration systems, mechanical energy is converted to heat energy by mechanically compressing a refrigerant, by means of a compressor; and since refrigerants have a fixed pressure-temperature relationship, much like saturated steam, altering the pressure of a refrigerant correspondingly alters its temperature. I've read of other methods utilizing friction, which is itself mechanical energy in the more pure and direct sense rather than the operation of a mechanical device which itself is utilizing electrical energy, but the compressor example is the only practical real-world application of this nature in common, everyday use that I can think of.
How does a mechanical wrist watch work?
Energy is stored in a wound up spring. The energy is released in a controlled manner by the use of gears, and turns the hands of the watch.
Does heat engines use heat to do work?
by engine
Heat engines use heat to do work?
Yes. Heat engines come in various forms. For example, internal combustion using gasoline or diesel, external combustion (not much used), steam engines reciprocating or turbine, gas turbines, rocket engines.
What is the use of steam engine?
To convert heat energy into mechanical work.
Can heat be converted other types of energy?
The most common method is to convert the heat into steam and use the steam to drive mechanical devices such as engines and turbines.
Define what do you mean by mechanical engineering and mention where are the application area of mechanical engineering mention at least in manufacturing and power production?
Mechanical engineering is concerned with the design, construction, and operation of power plants, engines, and machines. It deals mostly with things that move. One common way of dividing mechanical engineering is into heat utilization and machine design. The generation, distribution, and use of heat is applied in boilers, heat engines, air conditioning, and refrigeration. Machine design is concerned with hardware, including that making use of heat processes.
Does external combustion engines use turbines?
No,they use engines to produce mechanical energy.
How do heat engines use thermal energy and how do refrigerators keep things cold?
Heat engines transform thermal energy to mechanical energy. A refrigerator is a device that transfers thermal energy from inside the refrigerator to the room outside.
Is it possible to construct a heat engine that produces no thermal pollution?
Atmospheric engines, or 'Stirling' engines, can make use of waste or naturally occuring heat differences, to work.
Fossil fuel harness the energy?
fossil fuels are a type of renewable resources
When you rub your hands together on a cold day you use friction to convert what energy?
The friction force converts mechanical energy of the body into heat energy that is released. Work done by mechanical energy=Force x displacement =Heat produced.
Is it possible to construct a heat engine that creates no air pollution?
No, it is not possible to construct a heat engine that will not expel heat in to atmosphere. according to second law of thermodynamics, all the practical heat engines absorb heat from the source, convert a part of it in to mechanical work and reject the remainder to the cold body or atmosphere. hence, no heat engine can operate with single source for conversion in to mechanical work without expelling heat to the atmosphere. in other words, their must be a temperature difference between the hot and cold bodies (source and sink) for the conversion of heat in to mechanical work.Answer:Hot air is generally not considered a pollutant. Any system that creates mechanical or electrical energy without using fuel would be considered pollution free.A Sterling Cycle engine can use waste (recovered) heat to create mechanical energy. This creates no additional pollution and in fact, as it achieves higher efficiency in the original system, reduces additional fuel use and its associated pollution.Electricity can be generated directly from waste heat by thermocouples of dissimilar metals, again increasing efficiency.Waste heat can be used to boil water to steam for propelling turbines. This recovery creates no additional pollution.Steam from geothermal sources or from solar arrays can alo power engines and turbines without pollution.
How does mechanical toys work?
The mechanical toys can use rubber bands, springs and flywheels to make them work
