Can the actual mechanical advantage of a machine ever be greater then its ideal mechanical advantage?

- In real machines, there is always friction that reduces the efficiency of the machine.
- This reduces the mechanical advantage because some of the input force has to be used to overcome the force of friction in the machine.
- To reduce friction in the machine, you could add a lubricant such as oil.

∙ 12y agoBecause the "ideal advantage" doesn't always consider all factors i.e. gravity, friction, heat/cold etc. It considers just the "ideals".
Wiki User
∙ 10y agoSome of the theoretical advantage is lost as a result of friction, through which energy may be converted to heat or sound.
Wiki User
∙ 11y agoNo. "Ideal" in this case means "the maximum that can be achieved under ideal circumstances". Therefore, the real mechanical advantage will be less than or equal to the ideal.

The more efficient a machine is the closer the actual mechanical advantage is to the?
Perfect efficiency
What will increase the actual mechanical advantage of a machine?
Common mechanisms for obtaining mechanical advantage would include such as multiple pulleys, hydraulic systems, gears, and levers.
What are the units for actual mechanical advantage?
No units. It is a ratio
How does the size of a ideal mechanical advantage compares to the mechanical advantage?
This is because the actual mechanical advantage is the actual calculation found after dividing the effort force by the output force. Ideal mechanical advantage is what many people would call and estimate. When estimating mechanical advantage, the numbers are always rounded. This makes actual mechanical advantage less. Sources: Science teacher ------------------------------------------------------------------------------------------------------------------ The answer above is incorrect. The ideal mechanical advantage (IMA) is usually less than the mechanical advantage (MA) in a given machine because of the friction acting on the machine. There will always be some frictional resistance that increases the effort necessary to do the work.
How can two machines appear identical and yet not have the same actual mechanical advantage-?
They can't uless some parts are hidden from inspection.
What is the difference between actual machanical advantage and ideal machanical advantage?
Ideal mechanical advantage is what could be obtained without the effects of gravity and friction lowering the efficiency of the machine. The actual mechanical advantage is what can actually be obtained by the machine.
What happens to the mechanical advantage of a machine if friction is reduced through the use of oil or some other means?
Wear and tear of moving parts would be reduced. Less energy would be needed to run the machine, as there would be less friction to be overcome. A well lubricated machine is more efficient than a neglected machine with unoiled parts.
You test a machine and find that it exerts a force of 5 N for each 1 N of force you exert operating the machine What is the actual mechanical advantage of the machine?
The mechanical advantage is 5.Mechanical Advantage = Output Force/Input Force
Why do you multiply to find the total mechanical advantage?
The "Ideal Mechanical Advantage" of a simple machine isIMA = output force /input force . To find the 'actual' or real-world mechanical advantage,multiply the IMA by the machine's efficiency.
The more efficient a machine is the closer the actual mechanical advantage is to the?
Perfect efficiency
Distinguish between theoretical mechanical advantage and actual mechanical advantage How will these compare if a machine is 100 percent efficient?
When a machine is 100% efficient, theoretical and actual MAs are the same. Please let me know when you run across one of these.
What can be done to increase the efficiency of the machine?
Mechanical Efficiency is the ratio of Actual mechanical advantage to ideal mechanical advantage.Efficiency will be maximum when Actual mechanical advantage equals that of ideal.But practically not possible.Actual mechanical advantage will be less due to friction,heat,deflection etc.avoiding these loses will increase the machine efficiency.
What will increase the actual mechanical advantage of a machine?
Common mechanisms for obtaining mechanical advantage would include such as multiple pulleys, hydraulic systems, gears, and levers.
How does actual mechanical advantage compare with ideal mechanical advantage?
The actual mechanical advantage is usually less, due to losses.
What is the ideal and actual mechanical advantage of a machine?
we can save our time by using machines and a machine can perform the work of hundred men.
A 100 newton force applied to a machine lifts a 400 N object what is the actual mechanical advantage of this machine?
4
If a machine was 100 percent efficient how would the AMA compare to the IMA?
At perfect 100% efficiency, the Actual Mechanical Advantage should equal the Ideal Mechanical Advantage.
