My turn and this one is kinda different but there is 2 correct responses depending on the definition from the source you use. What type of simple machine is a flat head screw driver i want both answers.

[Sciolapedia]

It is a wheel and axle and a wedge

[helicpters_rule]

Sorry I should of clarified if you are using it to screw a screw.

[Sciolapedia]

But still im pretty sure it wouldn't be a screw

[Algorhythmic]

While a flat-head screwdriver acts a a wheel an axle to direct the outside forces of your hand to the central point below (the head), I wouldn't really count this as a wedge because it's not really the main purpose of the screwdriver. Sure, a screwdriver does have a wedged shape at the end, but that shape's purpose is to make placing it into the screw's notch a little easier than if its sides were just parallel.

[Sciolapedia]

I agree that wheel and axle is the main force and the wedge isn't. However other uses of the screwdriver could be as a wedge ,and since its a flathead it is easier as a wedge than other drivers

[Algorhythmic]

Yes, but if you're going to be that guy...

It's not the actual main purpose of screwdriver. If I was following that logic, I could just as easily say that a screw is a wedge because I can hit it with a sledgehammer into a block of wood. Just because something can be used as a wedge doesn't mean its a wedge.

[Sciolapedia]

That point makes sense. However since it is a flathead driver it has a triangular prism head shaped like a wedge. The shape resembles that of a knife or axe which r both wedges. I agree with u in the fact that it is not used as a wedge. But I think that it can be given its physical properties

[chinesesushi]

Going along with that logic, a screwdriver could also be used as a lever to pry open the top of can after wedging it in.

This should help http://www.merriam-webster.com/dictiona ... and%20axle read the definition of a wheel and axle and think if a screw driver fits THIS definition. (does it have a rope/chain)
