Examples of friction as a foe?
wear and tear the machine parts
Why do you say thst lubricating fluids control friction?
We say that because they do their job by allowing the parts of the machine to move more easily and produce less heat. That's what my teacher said.
What happens to the mechanical advantage of a machine if friction is reduced through the use of oil or some other means?
Wear and tear of moving parts would be reduced. Less energy would be needed to run the machine, as there would be less friction to be overcome. A well lubricated machine is more efficient than a neglected machine with unoiled parts.
How do ball bearings increase the efficiency of many machines?
they reduse the friction between the machine parts.
What simple machine reduces friction?
If I'm not mistaken, there is no machine that can reduce friction. The machine is intended to change the distance the input force is applied over or to multiply the output force. The moving parts of the machine will always increase friction. In order to reduce the extra friction (but not completely remove it), one would use a lubricant or reduce the roughness between two surfaces. Hope it helps.
Why is machine heated up when it runs for sometime?
Machines heated up due to the friction caused due to their running internal parts. That's's why machines are oiled or greased to reduce friction and to produce less heat
When is less friction deirable?
Moving parts in a machine.

What machine parts are used to reduce friction?
I think it would a lubricant not a part...
What machines use to lower friction between moving parts?
Ideal Machine
What do machines use to lower friction between moving parts?
Ideal Machine
What are disadvantages of heat produced by friction in machines?
energy used for the machine will get lost as heat .machine parts will get worn out.

We say that because they do their job by allowing the parts of the machine to move more easily and produce less heat. That's what my teacher said.
How do you increased machine efficiency?
By reducin friction between the machine parts and also by avoiding any sorts of power losses.

Why machine oil is put on moving parts of a machine?
To prevent the friction between them otherwise they will jam and there may be excess heating of parts due to frictionAnother reason to oil machine parts is to prevent rusting. IF a machine part is rubbing another so one has bare metal - it will rust quite quickly - so in addition to reducing friction and heat build up it prevents rust
