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 increases as efficiency of a machine increases?

As the efficiency of a machine increases, the output of the machine for a given input also increases. This means that the machine can do more work with the same amount of energy input. Additionally, the operating costs of the machine may decrease as efficiency improves, since less energy is wasted.


Explain why the amount of work that a machine does is less than the amount put into the machine?

The amount of work that a machine does is less than the input work due to energy losses in the form of friction, heat, and inefficiencies in the machine's operation. These losses result in some of the input work being dissipated and not translating fully into useful output work performed by the machine.


In a practical machine the power output is smaller than the power input. Considering the law of energy conservation what can explain this occurrence?

In a practical machine, energy losses occur due to factors such as friction, heat, sound, and vibration. These losses result in the power output being less than the power input, in accordance with the law of energy conservation. The dissipated energy usually ends up as waste heat, reducing the efficiency of the machine.


Can a machine be useful even if its mechanical advantage is less than one explain and give an example?

Yes, a machine can still be useful even if its mechanical advantage is less than one. This can happen when the machine reduces the amount of force needed to perform a task, even though the output force is less than the input force. An example of this is a pulley system, where the force needed to lift an object is reduced by distributing the load over multiple ropes and pulleys.


If the output work of a simple machine is than the input work the machine is said to have less than 100 percent efficiency?

Explain efficiency and how to calculate it for different simple machines?

Efficiency means to calculate that is the machine is efficient enough to save your bill or use less electricity. To calculate the formula is:Efficiency = Energy output (what is the machine producing) divided by Energy input (what is the machine taking or using).


Why is w out is always less than w in?

That is becasue no machine is 100% efficient - SOME energy usually gets wasted.

What is robotics engineering?

A robotics is a user defined programmable machine which is very efficient in performing the tasks given by the user according to the instructions given to the machine. The performance of these machines are very efficient and takes very less time to perform the given task when compare to the normal human.

How does the output work compared to the input work for a machine that has an efficiecny less then 100?

When a machine has an efficiency less than 100%, it means that not all of the input work is converted into output work. Some of the input work is lost as waste energy, usually in the form of heat or friction. This results in the output work being less than the input work applied to the machine.
