Q:

What simple machines make up a pair of scissors?

A:

Quick Answer

Scissors are composed of two different types of simple machines: wedge and lever. The scissors' blades are sharpened into wedges, and the arms that are squeezed together are levers.

Full Answer

There are six basic simple machines. These are the lever, screw, inclined plane, wedge, wheel and axle, and the pulley. The lever is used to lift an object, and it is more efficient when used with a fulcrum. The screw allows an object to move from a lower position to a higher one. It can also be used to hold objects in place. The inclined plane helps things go from either a lower position to a higher one, or a higher position to a lower one by moving up a ramp. The wedge is used to separate objects or hold them together. The wheel and axle allows objects to be moved by the wheel rotating around the axle. The pulley is used to lift or lower heavy objects.

  • Q:

    What are some simple machines?

    A:

    The six simple machines are wedges, screws, levers, pulleys, wheels and inclined planes. Simple machines make work easier by transferring force from one place to another, changing the direction of a force, increasing a force, increasing the distance of a force or increasing speed of a force. All of these forces move mass.

  • Q:

    What kind of simple machine is a pair of scissors?

    A:

    A pair of scissors is two levers put together. With this simple machine, less force is needed because a greater distance is involved. Other types of levers include a see-saw, a hammer, a fork and a baseball bat.

    What are some examples of six simple machines?

    A:

    Examples of six simple machines include windmills, slides, chisels, drills, blinds and seesaws. A windmill is a wheel and axle, slides are inclined planes, a chisel is a wedge, a drill is a screw, blinds are pulleys and a seesaw is a lever. Simple machines allow humans and animals to do work more easily by lessening the amount of force needed to move objects.

  • Q:

    What are seven simple machines?

    A:

    The seven simple machines are the inclined plane, wedge, screw, lever, pulley, gear and wheel and axis. The simple machines are non-powered mechanical devices that change the direction or magnitude of a force. Each of these machines is considered to be a simple machine. However, when combined, they are considered a complex machine.
