Well, if, for example, you had interlocking gears, the friction would slow down the speed of how they turn. Friction also causes heat, so too much friction could make a computer or a more advanced machine, melt inside. I think that DEFINETELY affects the work of a machine.

What factor affect the mechanical advantage of simple machine?
friction affects the M.A in a simple machine.
In any machine some work is wasted overcoming?
Friction.
Why is it impossible for the output work of a machine to be greater than the machine's input work?
There are always energy losses within the machine due to inertia, friction, etc.
Does an ideal machine have friction?
Machine without any friction is an ideal machine so an ideal machine cannot have friction.
Why would machines work better without friction?
The smaller amount of friction a machine has, the more efficient it becomes.
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.
How does work affect friction?
work is movement, and all movement causes friction, since there is no such thing as a "perfect" or "100% efficient" tool yet.

How does the output work done by machine change when friction is reduced?
Increases
Does an ideal machine have friction?
Machine without any friction is an ideal machine so an ideal machine cannot have friction.
Why would machines work better without friction?
The smaller amount of friction a machine has, the more efficient it becomes.
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.
Friction changes the useful work of a machine into mechanical energy true or false?
true
How does the output work compared to the input work for a machine that has an efficiecny less then 100?
the efficiency of any machine is NOT 100% because some of the input work is used to compensate for the work done by friction.
