OT ....do you know"

There are seven basic tools that just about everything mechanical use in one form or the other to function. Before you run to web see if you can remember. I'm sure there are 7 but I can't remember all of them.

I know where you're coming from, and I know how you got here. But there are only four (three technically, though the derivatives are sketchy at best).

8 pound beater.
sleever bar
2 ton come-a-long
duck tape
sharp knife
fork lift
C4
.45acp


that's 8

I know that .45 ACP makes a pretty good drill for installing appropriately sized bolts in wood 2x4's. Friend of mine did that one day when someone walked off with the cordless drill and wouldn't bring it back.

Pumpkinhead.......Actually I guess there is only three basic but combinations of them take it to six. No wonder I couldn't remember seven...well, at least......that's my excuse

Well, I'll have to dispute even six, because the wedge and screw are both inclined planes.
And I dispute the technical three (inclined plane, lever, and wheel) to include the pulley, which some classify as wheel and axle. But a wheel and axle gives no mechanical advantage other than friction reduction (using a barrow instead of dragging a load), conversion of force (barrow wheel rotating as load is moved linearly), while a pulley (compound, block & tackle) reduces linear effort.

[monte55]

I have to agree. Even the standard toothed gear engaged with another is wheel and axle and lever.

As commonly defined, the 6 basic machines are:

Screw

Inclined plane

Lever

Wedge

Wheel and axle

Pulley

And no, I didn't know this off the top of my head. I had to look it up. Here is one source..... http://www.fi.edu/qa97/spotlight3/spotlight3.html
