To find the mechanical advantage of a simple machine divide output force by input force. (input force is the force that we exert on a machine, and output force is the force that is exerted by a machine).
you have to multiply the individual mechanical advantages of all the simple machines that make up the compound machine.

I believe a bridge should be considered a simple machine. It saves work and gives mechanical advantage. It can also shorten distance, so unlike an inclined plane it can benefit without increasing distance. It can bypass the need to raise and lower massess into crevasses, it can bypass long journeys down then back up a hill. I could find no discussion anywhere.
The efficiency of a machine is found by considering the useful energy or work that comes out of it, and dividing this by the work that you put into it. Multiply by 100 to get the answer in terms of percentage. You should never get more than 100% efficiency, or 100%, since energy will be lost (to heat caused by friction for example).

The elbow in the hand is analogous to the fulcrum in a lever
well, your obviously not doing it right you have to want to have to use to look more like and if you do that you will find your answer i promise Well that made no sense. Basically, the fulcrum is where everything hangs from or balances on. The thing that holds up a see-saw in the middle, for example.
There are four simple machines used to make the compound machine known as the lawn mower. These simple machines are the wheel and axle, the screw, the lever, and the wedge.
Almost everywhere!!!
you can find it in Wallmart
All you have to do is fine a simple task to do and find simple machines and connect them together to make it. All you have to do is fine a simple task to do and find simple machines and connect them together to make it.
The mechanical advantage that a machine would have without friction or in another term is that you can find the IDEAL MECHANICAL ADVANTAGE (IMA) OF A MACHINE IS BY HAVING A MACHINE WITH NO FRICTION, ALSO BY MULTIPLYING YOUR EFFORT FORCE BY 2, HOWEVER BECAUSE OF FRICTION AND THE WEIGHT THE ACTUAL MA WILL BE LESS.
