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.
Why is the actual mechanical advantage of a machine different for a machines ideal mechanical advantage?
The actual mechanical advantage of a machine is usually less than its ideal mechanical advantage due to factors like friction, energy loss, and imperfections within the machine. These losses reduce the efficiency of the machine in transferring input force to the output force. Ideal mechanical advantage is based on the design and geometry of the machine, while actual mechanical advantage accounts for real-world limitations and performance.
What is true about the mechanical advantage of a machine a it increases with greater friction b it decreases as the input distance increases c it is less than the idle mechanical advantage?
c) It is less than the idle mechanical advantage. The actual mechanical advantage of a machine is always less than the ideal mechanical advantage due to factors like friction and energy losses in the system.
Why is the ama of a machine always less than the ima of a machine?
The actual mechanical advantage (AMA) of a machine is always less than the ideal mechanical advantage (IMA) due to factors such as friction, inefficiencies in the machine's design, and other losses of energy. As a result, the actual output force of a machine is typically less than the input force required to operate it, leading to a lower actual mechanical advantage compared to the ideal mechanical advantage.
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.
For a given machine explain why the MA is usually less than the IMA?
The mechanical advantage (MA) is usually less than the ideal mechanical advantage (IMA) for a machine due to factors such as friction, inefficiencies in the machine's design, and energy losses through heat or sound. These factors cause the input work to be greater than the output work, resulting in a lower actual mechanical advantage compared to the ideal mechanical advantage.
What happens to the mechanical advantage of a machine if friction is reduced through the use of oil or some other means?
If friction is reduced through the use of oil or another means, the mechanical advantage of the machine would typically increase. This is because less energy is lost to friction, resulting in more efficient operation and a greater output force compared to the 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.
If you know the input distance and output distance of a machine which of the following can you calculate?
Type your answer here... The actual mechanical advantage.
The more efficient a machine is the closer the actual mechanical advantage is to the?
Perfect efficiency
How is the actual mechanical advantage of a machine determined?
The actual mechanical advantage of a machine is determined by comparing the input force applied to the machine to the output force it produces. It is calculated as the ratio of the output force to the input force, taking into account any inefficiencies or energy losses in the machine.
How does the ideal compare with the actual mechanical advantage?
The ideal mechanical advantage is based on the geometric relationships of a machine's components and assumes no energy losses, while the actual mechanical advantage accounts for friction, inefficiencies, and other factors that can reduce the output compared to the input force. In reality, the actual mechanical advantage is always less than the ideal mechanical advantage due to these energy losses.
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. This means that for every 1 N of force you exert, the machine will output 5 N of force.
