How well a machine changes effort into work?

Efficiency


The mechanical advantage of a machine is always greater than 1?

well the advantage of that is pie, not math pie but pie that you eat


Work input equals work output is what type of machine?

Such as machine is said to have an efficiency of 100%. Since some type of energy loss is unavoidable, this is not possible in real life, but in some cases it can be approximated quite well.


Why can't mechanical efficiency be over 100 percent?

The mechanical efficiency can't be over 100% because a type of energy is always lost. For example, it can be lost as heat, sound or even light. When you use a light bulb, it produces light, but heat is lost in the process. See what I mean! In most cases, heat is lost due to friction. the work put out by a machine is always less than the work put into a machine to do the work. Therefore no machine is 100% efficient. As well.... Efficiency is (power out/power in) x 100. To get an efficiency of *more* than 100%, the machine must give more power out than is put in. No machine has ever been demonstrated that does this, and until someone can show this result (power out *more* than power in), we know that any machine has an efficiency less than 100%.


Explain how much efficiency of an ideal machine compares with the efficiency of a real machine?

An ideal machine has, by definition, an efficiency of exactly 100%, which means that absolutely none of the energy it consumes is wasted when converted to power (energy per unit of time), hence the name "ideal". A real machine, however, will never reach an efficiency of 100%, as there will always be at least a tiny bit of energy that is lost to the environment. This is because it is practically impossible to create a perfectly closed system in which no energy can leak out. It is possible, however, to build very efficient systems and machines, although this depends on just how well they are made. Therefore, the efficiency of a real machine is quite variable, going easily from 10% to 98%, depending on its quality. A simple example is that of ordinary household voltage transformers, which generally have efficiencies of around 80%; and of high grade power plant transformers, which have efficiencies of around 98%.

Does a bigger wheel increases the efficiency of the machine in the wheel and axle?

Generally automobiles are designed with optimum size wheels. Changing the diameter is unlikely to increase efficiency, and could well have the opposite effect.
