No.

A perfectly frictionless machine could have an efficiency of 100%.

Anything less perfect must have can efficiency less than 100%.

Do idler pulley change the direction of rotation?

Yes, idler pulleys can change the direction of rotation in a belt-driven system. They are used to guide and tension the belt, allowing it to reroute around obstacles or to achieve the desired alignment of components. While the idler pulley itself does not directly drive any load, its placement can effectively alter the path of the belt and the direction of the rotational motion transmitted through the system.


Why does the shaping tool move faster during the return stroke?

During the return stroke it does not remove any material, it is an idle stroke so to improve the cutting efficiency it will move faster during the return stroke. Pradip Kotak.


What machines uses ac?

AC (alternating current) is commonly used in various machines and appliances, including household items like refrigerators, air conditioners, and washing machines. It powers industrial machinery as well, such as motors and conveyor systems, due to its efficiency in transmitting power over long distances. Additionally, AC is used in lighting systems, including fluorescent and LED fixtures. Overall, any device that requires consistent power supply typically employs AC for its operation.


What is a snap choke core?

It is a ferrite core over coax cable, AC or audio cord. It prevents electro-magnetic interference (EMI) and cuts down on radio-frequency interference (RFI).Prevents electric magnetic interference (EMI) and cut down on radio frequency interference (RFI)Simply snap it over any coax cable, AC or audio cordRoSH compliant


Is there a backup wrench made for castellated nuts?

No, they are made for use with regular or box wrenches. In over 40 years of working t=with them,I've never seen any 'backup wrench' and can't even think why you would want one.

Can a car have a 100 percent efficiency?

No. Nothing mechanical can ever have a 100% efficiency by any physical evaluation.


What efficiency is assumed when calculating the ideal mechanical advantage?

The assumed efficiency is 100% without any friction


Why a normal machine could not have the mechanical efficiency of 100?

Because there is always going to be friction, the efficiency of any machine will always be less then 100 percent.


How much weight can a pulley lift?

The amount of weight a pulley can lift depends on factors such as the design of the pulley system, the strength of the rope or cable used, and the efficiency of the pulley itself. However, a single fixed pulley does not provide any mechanical advantage and can only lift as much weight as is being applied to it.


What is the efficiency of a device that gives you 100 units of useful energy for every 100 units you put in it?

The efficiency of the device is 100%. This means that all the energy input into the device is converted into useful energy output without any loss.


What is the maximum efficiency any machine can have?

Mathematically, efficiency = (energy output) divided by (energy input) as a percentage. As if we couldn't figure this out for ourselves, one of the laws of Thermodynamics formally tells us "You can't get more energy out than what you put in." Applying this law to the formula for efficiency, it says that the maximum possible efficiency is 100%. However, the next law of Thermodynamics says "You can't even get that much out."


What is 32 over 100 as a percent?

Any number over 100 is automatically that percent. For example, 32 over 100= 32% 50 over 100= 50% 98 over 100= 98%


What is Machine with 100 efficiency?

A machine with 100% efficiency would output the exact same amount of energy it takes in, without any losses. This would mean that all the input energy is successfully converted into useful work output. However, achieving 100% efficiency in practice is impossible due to factors such as friction, heat loss, and other inefficiencies.


Why doesn't any system have 100 percent efficiency?

frictionIn real machines, as opposed to ideal machines, there is always friction that reduces the efficiency of the machine. Lubricants like oil can be used to reduce friction and improve efficiency.


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%.


What is the maximum efficiency of a machine?

The maximum efficiency of a machine is 100%, which means that all input energy is converted into useful output energy without any losses. However, achieving 100% efficiency is practically impossible due to factors such as friction, heat loss, and other inefficiencies in real-world systems.


Why is is that is impossible to have a 100 percent efficiency?

It is impossible to achieve 100 percent efficiency due to various factors such as friction, heat loss, and energy conversion losses. These factors result in some amount of energy being wasted in any process, making perfect efficiency unattainable.
