What else can I help you with?
The more efficient a machine is the closer the actual mechanical advantage is to the?
Perfect efficiency
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.
If a simple machine could be fricionless how would its IMA and AMA compare?
If a simple machine were frictionless, its Ideal Mechanical Advantage (IMA) would be equal to its Actual Mechanical Advantage (AMA). This is because IMA is calculated based on the machine's geometry and assumes no energy losses, while AMA accounts for real-world efficiencies, including friction. In the absence of friction, there would be no energy loss, making IMA and AMA identical. Thus, in a frictionless scenario, both values would be the same.
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.
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 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.
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 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.
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.
Actual mechanical advantage is the output force of what?
Actual mechanical advantage is the ratio of the output force to the input force in a simple machine or system. It is a measure of how much a machine amplifies the input force to produce the desired output force.
What is the actual mechanical advantage?
The actual mechanical advantage is the ratio of the output force to the input force in a machine. It is calculated as the ratio of the resistance force to the effort force. It provides insight into how much a machine amplifies or diminishes the force applied to it.
