How does the output work done by machine change when friction is reduced?
Increases
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.
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.
Does the simple machine reduce overall work needed?
No. Work out is always less than work in due to friction and other losses..
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.
What increases the work output of a simple machine?
Increasing the input force or the distance over which the force is applied can increase the work output of a simple machine. Reducing friction within the machine can also help to increase its efficiency and work output.
What causes the output work of a machine to e less than the input work?
Some of the input force is lost due to friction. If you are using a pulley system then there is friction between the rope and the pulley and there is also friction within the ball bearings of the pulley itself. If you are using an inclined plane there is friction between the plane and the object traveling upon it. In a friction-less world the input is equal to the output.
Is the work output of a machine is always less then the work input where does the missing work go?
The energy, lost to friction, is converted to heat and sound.
Can you work on friction less floor?
No, We cannot do work on friction less surface
How is the work output of a machine related to it's work input?
In an ideal universe, where there are no friction or heat transfer losses, work out = work in. In our universe, however, work output is always less than input. How much less depends on the efficiency of the machine's design.
Reducing friction increases the ideal mechanical advantage of a machine?
Reducing friction helps to minimize energy loss, making the machine more efficient. This allows the machine to transfer more of its input force or energy into useful work, increasing its ideal mechanical advantage.
Which factor increases as the efficiency of a machine increases?
The output work done by the machine increases as the efficiency of the machine increases. This is because efficiency is the ratio of useful work output to the total work input, so as efficiency increases, more of the input work is converted into useful output work.
