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.
What effect does friction have on a machines efficiency?
Efficiency of the machine is reduced due to loss of energy by friction.
What is a comparison of a machines work input and work output?
mechanical efficiency
How is a machines mechanical efficiency is calulated?
Work Output/Work Input X 100
What is the name of the machine of the force that prevents machines from operating at 100 percent efficiency?
Friction.
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 does friction reduce the efficiency of machines?
Friction requires energy to overcome it. This causes loss of energy in the system. Loss of energy in a system, by definition, is a reduction of efficiency.

What effect does friction have on a machines efficiency?
Efficiency of the machine is reduced due to loss of energy by friction.
What do you do to reduce cost to serve?
Either improve efficiency or reduce quality
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 is a comparison of a machines work output and work input?
mechanical efficiency
What reduces the efficiency of machines?
It would be friction.<3 hope this helped
What is a comparison of a machines work input and work output?
mechanical 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.
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?
