The mechanical efficiency can't be over 100% because a type of energy is always lost. For example, it can be lost as heat, sound or even light. When you use a light bulb, it produces light, but heat is lost in the process. See what I mean! In most cases, heat is lost due to friction. the work put out by a machine is always less than the work put into a machine to do the work. Therefore no machine is 100% efficient. As well.... Efficiency is (power out/power in) x 100. To get an efficiency of *more* than 100%, the machine must give more power out than is put in. No machine has ever been demonstrated that does this, and until someone can show this result (power out *more* than power in), we know that any machine has an efficiency less than 100%.
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.

I would say that the output would be less. What would you think? Actually it matters what machine your talking about but hopefully ur output work would be more then your input work because that would mean the machine is doing more. This would mean its more efficent
a pump is driven by the engine of the machine and is linked to the speed set by the operator. It pumps a constant stream of high-pressure oil to the motor. Since the motor is linked to the drive wheels or tracks of the machine, it gives the machine its travel speed.

Its a simple machine machine i could see where your coming from thinking it is a compound machine. But i mean it is simple. Now i know a couple stores have compound machine
The input force is called the 'effort.' It doesn't mean that we are supplying force to the machine when we are using it but we supply power to the machine using fuel and something else. But when the machine runs it has the horizontal force on it, hence it has K.E. Remember the law of conservation of energy.
