The answer lies in "Wheel and Axle". Steering wheel is is example for mechanical advantage. Door knob is also another example. This is a class 1 lever. But the same principle has not so far been utilized to manufacture turbines. I have designed a turbine utilizing wheel and axle example. This is known as "CHALASANI TURBINE". The characteristic feature of this turbine is that output exceeds input. The mechanical efficiency of the turbine will be more than 100%. The turbine can be designed with an efficiency rate of 200%, 1000% etc. When the output exceeds input, pumps can be used to cause the motion of the turbine in a closed circuit. In other words, the given mass of water can generate required quantum of power. In this system, to start the system energy has to be taken from the external sources. But once the system is started, it supplies energy not only for the self maintenance but also to the external load. We can generate energy to the social requirement. To clearly understand this concept please see my entry in "NASA techbriefs.create the future design contest 2010" in sustainable technologies.
In a mechanical advantage system, the force is multiplied by the factor of the mechanical advantage. The formula for mechanical advantage is MA = output force / input force. This means the force can be multiplied by the mechanical advantage value.
Mechanical advantage is determined by physical measurement of the input and output forces and takes into account energy loss due to deflection, friction, and wear. The ideal mechanical advantage, meanwhile, is the mechanical advantage of a device with the assumption that its components do not flex, there is no friction, and there is no wear.
Time can be used to measure mechanical advantage by comparing the time taken to perform a task with and without a mechanical advantage device. If a mechanical advantage device reduces the time required to complete a task, it indicates that the device has increased the efficiency of the task, thereby providing mechanical advantage.
The amount by which a machine multiplies an input force is called mechanical advantage. It is calculated by dividing the output force by the input force.
Efficiency of a machine or mechanical advantage
The mechanical Advantage is FORCE TIMES DISTANCE
The actual mechanical advantage is usually less, due to losses.
Mechanical Advantage;The ratio of load and effort is called mechanical advantage of any machine.Mathematical Formula Of Mechanical AdvantageMechanical Advantage = Load / EffortUnit Of Mechanical AdvantageAs mechanical advantage is the ratio of two forces, therefore it has no unit.
The mechanical advantage is when the fulcrum is closer to the effort and creates a advantage
Mechanical advantage the resistance force. Mechanical advantage is equal output force divided by input force.
Mechanical advantage equals resistance force.
In a mechanical advantage system, the force is multiplied by the factor of the mechanical advantage. The formula for mechanical advantage is MA = output force / input force. This means the force can be multiplied by the mechanical advantage value.
Mechanical Advantage: F(out)/ F(in) Actual Mechanical Advantage is the ratio of Force outputed to Force inputed. (AMA=Fo/Fi) Similarly, IMA (Ideal Mechanical Advantage) = di/do
Mechanical advantage=load/effort
it is less than the ideal mechanical advantage
Mechanical Advantage = Effort/Load
775 is a number, not a machine. It, therefore, has no mechanical advantage.
