What is the work output of a machine never equal to the work input?
It is usually less. The reason for this is that some energy is usually lost (wasted) in the machine.
Explain why the amount of work that a machine does is less than the amount put into the machine?
Output work is always less than input work.
Does a machine decrease the amount of work done?
Yes, usually it will decrease it, since no machine is 100% efficient.Just in case you mean "the amount of work REQUIRED", then of course the machine will INCREASE that.
How do you calculate for the injection machine capacity?
The capacity for injection machine has something to do with the injection machine screw volume. Usually one injection machine offers option for 3 or more screw with different volume. The injection weight= volume*density of plastic material. The product weight should be less than 80% for the theoretical injection machine capacity.
What simple machine has an IMA less than 1?
simple machine.
What is the work output of a machine never equal to the work input?
It is usually less. The reason for this is that some energy is usually lost (wasted) in the machine.
Explain why the amount of work that a machine does is less than the amount put into the machine?
Output work is always less than input work.
Why is work output by a machine always less than the work input?
It is usually unavoidable that some energy is wasted.
Explain the meaning the first shall be last.?
Those who are given much recognition on earth will be of less importance in heaven. and those who are given least recognition will have greater recognition in heaven.
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 a machine with efficiency of less than one?
no machine has one
Explain the distinction between location and place?
Sometimes location means exact position, while place is usually much less precise.
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.
Does a machine decrease the amount of work done?
Yes, usually it will decrease it, since no machine is 100% efficient.Just in case you mean "the amount of work REQUIRED", then of course the machine will INCREASE that.
Why is the amount of that a machine does is less than the amount put into the machine?
In such a machine, the remaining energy is wasted to friction
Does a machine do less work when friction in a machine increases?
Yes. Since more work goes to counter the friction force, less work goes to do the actual function of the machine.
