Can the actual mechanical advantage of a machine ever be greater then its ideal mechanical advantage?
In real machines, there is always friction that reduces the efficiency of the machine.This reduces the mechanical advantage because some of the input force has to be used to overcome the force of friction in the machine.To reduce friction in the machine, you could add a lubricant such as oil.
How does the size of a ideal mechanical advantage compares to the mechanical advantage?
This is because the actual mechanical advantage is the actual calculation found after dividing the effort force by the output force. Ideal mechanical advantage is what many people would call and estimate. When estimating mechanical advantage, the numbers are always rounded. This makes actual mechanical advantage less. Sources: Science teacher ------------------------------------------------------------------------------------------------------------------ The answer above is incorrect. The ideal mechanical advantage (IMA) is usually less than the mechanical advantage (MA) in a given machine because of the friction acting on the machine. There will always be some frictional resistance that increases the effort necessary to do the work.

How can two machines appear identical and yet not have the same actual mechanical advantage-?
They can't uless some parts are hidden from inspection.
Mechanical Engineering BTech?
its available in some universities. some other universities offers BE in mechanical engg.

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.

What is the mechanical advantage of a simple pulley?
If the pulley is fixed to the ceiling and the rope passes over it, then the ideal MA is 1, but there's some friction loss in it. If one end of the rope is fixed to the ceiling and the load hangs from the pulley, then the ideal MA is 2.
What is the difference between mechanical advantage and Efficiency?
A mechanism with a positive mechanical advantage is one in which the input force is greater than the output force. This is compensated for by the fact that the distance moved by the input is greater than the output so that in an ideal machine, the work input (Force*Distance) is the same as the work output. In real life, though, you always lose some energy - in the form of frictional heat, or sound.A negative mechanical advantage is the opposite. A small distance moved by the input is converted to a large distance moved by the output. But the force in the output is correspondingly reduced.A mechanism with a positive mechanical advantage is one in which the input force is greater than the output force.

If there was no friction what would that do to mechanical advantage and how would it affect efficiency?
Without friction, some forms of mechanical advantage do not function. In most cases for a mechanical apparatus, a reduction in friction is usually accompanied by an increase in efficiency.
What are some examples of thermal expansion?
a Mercury thermometera mechanical thermostat
When can the mechanical advantage be equal to the VR?
Decades of precise and repeatable experiments have failed to find a case in whichthey are not equal. Some observers have gone so far as to suggest that it is a lawof nature that these two quantities are in fact always equal, and that their equivalenceis quite independent of the efficiency of the machine.==========================================================Exactly ! The theoretical Mechanical Advantage that you would expect orlike to get is termed the "Ideal Mechanical Advantage", and the asker asked"When is the ideal ... equal to the ideal ... ?" I claim that this singlequantityis equal to itself always and under all conditions, and I said so in my response.To take up the matter of what M.A. you would actually realize in a real-worldmechanical system is entirely beyond the letter of the question. I strive at alltimes to avoid answering a question that was not asked. In other words, whenI respond to the Question "What time is it ?", I resist the instinct to describethe history, design, manufacture, and home construction of clocks.As you so perceptively point out, the question is meaningless. I tried to deliveran answer that responded appropriately.
Is it good to have a high mechanical advantage?
It may be good in some cases. A high mechanical advantage comes at a cost - you need to apply less force, but you need to apply it over a greater distance.

What are some mechanical wave?
Mechanical wave needs a medium to travel. Examples :- Sound Wave, Seismic Wave etc.
