Yes, it is true that almost every machine uses some of its work input to overcome friction. Friction is a force that opposes motion and can cause energy losses in a system, which often results in the need for extra work input to maintain operation. Reducing friction through lubrication or design improvements can help optimize machine efficiency.
What else can I help you with?
Is the efficiency of a machine is 60 the percentage of work input used to overcome friction?
No, efficiency of a machine is a measure of how well input energy is converted into useful output work, and is calculated as useful work output divided by total work input. The percentage of work input used to overcome friction would be related to the frictional losses in the machine, not the overall efficiency.
How does increased friction affect the actual mechanical advantage of a machine?
Increased friction reduces the actual mechanical advantage of a machine because more of the input force is used to overcome friction rather than move the load. This results in less of the input force being effectively transferred to the load, decreasing the overall efficiency of the machine.
Is it true or false that friction reduces the efficincy of a machine?
True. Friction causes resistance within a machine, leading to loss of energy in the form of heat. This decrease in efficiency can result in the machine requiring more energy input to overcome friction and perform its intended task.
What force is extered on a machine?
The force exerted on a machine is typically the input force applied by a person or a mechanical system to make the machine perform work. This force is used to overcome resistance within the machine, such as friction or a load being lifted. The output force produced by the machine is the result of the input force acting on the machine's components.
What is the effect of reducing friction on a machine's efficiency?
Reducing friction in a machine can increase its efficiency by allowing parts to move more freely, requiring less energy input to overcome resistance. This can lead to reduced wear and tear on machine components and lower energy consumption, ultimately improving performance and longevity.
Why is the work output of a machine never to the work input?
Some work input is used to overcome friction.

When a machine drills holes in metal some of the work input is used to overcome what?
Friction :) it says so in in my science book.

Why is the work output of a machin never equal to the work input?
Some work input is used to overcome friction.
Why does the input force have to be greater than the force needed to lift the bale?
The input force needs to be greater than the force needed to lift the bale because some of the input force is typically lost due to inefficiencies in the machine or due to friction. Having a greater input force ensures that there is enough force to overcome these losses and still lift the bale.
What is the difference between a ideal machine and real machine?
In ideal machine input is equal to output . The efficiency of ideal machine is 100% . In real machine input is not equal to output .The efficiency of ideal machine in not 100% . In ideal machine there is no lose of energy . In real machine there is lose of energy . In real machine there is no friction . While in real machine there is friction .
Force of an object that may be overcome by the application of a machine?
The force that may be overcome by the application of a machine is the input force. This force is applied to the machine to produce an output force greater than the input force, allowing the machine to perform work on an object. The machine acts as a force multiplier by changing the direction or magnitude of the input force to achieve a desired outcome.
