The mechanical advantage is greater for thinner wedges. However, the efficiency is low because of the large amount of friction.
A pushpin is a wedge because it has a sharp point ahead of a broader shank, and because this structure can be used as a wedge. The sharp point can be forced into material (which is what a wedge does), and the shank will follow it in as material is pushed aside in the process.
A high efficiency machine will produce more of what is it that you want with the same power as the low efficiency one. In other words, for a low efficiency machine do as much as a high efficiency one, you have to give it more power (energy).
Yes,Because crowbar has a slating sharp edge on its end.
A chisel is a wedge because it is used in carving wood.
Anything that isn't a wedge, really. An example of a wedge is an axe. A thing with that shape is a wedge. Non examples could be other simple machines: screws, levers, pulleys, really anything that, if you look in an encyclopedia, isn't classified as a wedge. :) .
The efficiency of a wedge is determined by the ratio of output force to input force. It is calculated as the length of the slope divided by the thickness of the wedge. The ideal mechanical efficiency of a wedge is 50%, assuming there are no energy losses.
I highly doubt it.
The efficiency of a wedge is calculated by dividing the load distance by the effort distance, then multiplying the result by 100 to get a percentage. The formula is: Efficiency = (load distance / effort distance) x 100. This gives you the ratio of the load distance to the effort distance, indicating how efficiently the wedge can lift or separate objects.
The efficiency of the the body is low when you are shivering because your body is in hibernation mode, shivering to help you maintain your body temperature.
Bounce is the angle of the sole to the ground. A lower bounce wedge will perform better on courses with tight lies, fairway shots and tight compacted sand. Typically a Low Bounce wedge will be in the 0-10° range.
They are not. Low E bulbs are low ENERGY, not low efficiency. They are actually highly efficient.
A high efficiency machine will produce more of what is it that you want with the same power as the low efficiency one. In other words, for a low efficiency machine do as much as a high efficiency one, you have to give it more power (energy).
Good Politician having low efficiency is better because atleast something positive will come out however slowly but Bad Politician With Great Efficiency is a disaster because he/she will lead the progress in negative direction & that too with full efficiency. :)

yes, because a doorstop wedges the door. So it would be a wedge.

b.)Its quiescent current is low
