What kind of lever is a paperclip? Is it a first class or second class lever?

Actually, it is a third class lever. The spring force is acting very close (radius of the wire) to the fulcrum, and the load is a significant fraction of an inch away.

I remember being told that a gram is approx the weight of a paperclip.  So unless you are weighing very small, light things I'd go w/kilogram.

That would be the paper-clip.

They don't chase for a penny.\n\nIf someone posts something with insufficient postage for 1st, it'll go second class. So you'd be wasting money.\n\nIf there's not enough for 2nd class, even if it's 1p short, you get a card through the door instead.\n\nThis card will inform the recipient that if they want their letter they have to pay a POUND, plus the missing postage. So you either have to take the card to the sorting office or post it with enough stamps to pay the fee.

stop buying paperclips!\nJust let them reproduce in the desk drawer!

Try what is said above, could be something simple. Also, you may need to open it up and look around. I not ever looked at one like yours, but, it has to have a way of feeding the Paper, gears, stepper motor. Look for worn, loose parts or a slipping gear in that area.

Magic Wand is the selection tool in photoshop.\nSelect the magic wand tool from the toolbar.\nThe property of the tool is that it selects the similar areas. So the editing of the images can be easy if you are able to select the similar areas. But the question here is, how does it select the similar area or how can we control the behaviour of the tool if it does not produce the desired result. The answer to the question is that there is a parameter called tolerance. You can play with this value to get the tool working as per your needs.\n\n\n\nI hope this will be helpful

I would imagine that the simple machine that you are looking for is a cam.  If you look up at the top of the  pole that the carousel there is a rotating bar that has a U shaped bend in it that the pole is attached to.  This U shape will raise and lower the horse as the rotating bar rotates.  It is like the crankshaft in a car.  I would imagine that the rotating bar has a gear at the end that is turned by a larger stationary gear as the platform of the carousel rotates.

1 The hinge is the fulcrum of a lever. A lever requires less force to move the same weight the farther you are from the fulcrum\n\n2 a pulley\n\n3 Friction is resistance against applied force and requires additional energy to overcome thus reducing efficiency.. \n\n4 The axe is a wedge.  The wedge is also an inclined plane. An inclined plane uses more energy the steeper the angle. Sharpening the wedge reduces the angle.\n\n\nGood luck in your study of simple machines.
