What factor prevents a machine from operating at 100 percent efficiency?
Friction is one factor that prevents a machine from operating at 100 percent efficiency. Some energy is lost as heat due to friction between moving parts, which reduces the overall efficiency of the machine.
Why a high-efficiency machine is more desirable than a low- efficiency machine?
High-efficiency machines do more for less and are therefore more desirable than a low-efficiency machine.AnswerHigher efficiency means lower energy losses and, therefore, such machines are more economical than low-efficiency machines.
How is a machines mechanical efficiency is calulated?
Mechanical efficiency of a machine is calculated by dividing the actual output of work by the theoretical output of work, and then multiplying by 100 to express it as a percentage. It is expressed as: efficiency = (Actual output / Theoretical output) * 100%. A higher mechanical efficiency indicates that the machine is operating more effectively with less energy loss.
What is the force that prevents all machines from being 100 percent efficient?
Friction is the force that prevents all machines from being 100 percent efficient. It produces a resisting force that hinders the machine's complete functioning. Reducing friction will enhance efficiency.
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 is a machine operating other machines called?
automation.
Describe why a high-efficiency machine is more desirable thana low-efficiency machine?
A high efficiency machine will produce more of what is it that you want with the same power as the low efficiency one. In other words, for a low efficiency machine do as much as a high efficiency one, you have to give it more power (energy).
What compares a machines work output with the work input?
That is called the machine's efficiency.
What compares a machines work output with work input?

Why doesn't any system have 100 percent efficiency?
frictionIn real machines, as opposed to ideal machines, there is always friction that reduces the efficiency of the machine. Lubricants like oil can be used to reduce friction and improve efficiency.

Why is the mechanical efficiency of most compound machines lower than most simple machines?
It is lower because compound machines have more moving parts that a simple machine does.
Does an ideal machine have an effciency of 100 percent?
No, an ideal machine cannot have an efficiency of 100 percent. This is because some energy is always lost as heat due to factors like friction and resistance. The best an ideal machine can achieve is an efficiency of 100% by having no energy losses.
