Simple Machines (engineering)

A simple machine is a mechanical device that can help you change the force applied to help do more work easier. There are six simple machines: Wheel and axle, pulley, inclined plane, wedge, and screw.

What machine does Steelo Brim use on Ridiculousness?

I think it's for show in that Steelo actually doesn't control the video at all.

What should I do for my simple machines project?

something that pulls up a tissue or crushes a grape of turns on something or rolls a marble

you can also look up on youtube simple machine projects;D

How do you build a k'nex wagon?

Add some simple wheel by using 8 sided connecters or gears. Then build around that where your imagination takes you. It is actually very simple.

What is magnetic arc blow?

Most stick welding SMAW is done with Direct Current DC. As this current passes thru the base metal it can set up a circular current on either side of the weld area creating a magnetic effect. The arc is affected by this and whips back and forth drawn by this magnetic field. Metal is blown out of the arc and splatters onto the sides of the weld and the arc is hard to control. This arc blow can be reduced by passing a separate magnetic field thru the metal nullifying the effect, or by welding in the opposite direction, or by using Alternating Current AC

What are the 6 kinds of simple machines?

A lever is a simple machine that consists of a rigid object (often a bar of some kind) and a fulcrum (or pivot). Applying a force to one end of the rigid object causes it to pivot about the fulcrum, causing a magnification of the force at another point along the rigid object. There are three classes of levers, depending on where the input force, output force, and fulcrum are in relation to each other. Baseball bats, seesaws, wheelbarrows, and crowbars are types of levers.

Wheel & Axle:

A wheel is a circular device that is attached to a rigid bar in its center. A force applied to the wheel causes the axle to rotate, which can be used to magnify the force (by, for example, having a rope wind around the axle). Alternately, a force applied to provide rotation on the axle translates into rotation of the wheel. It can be viewed as a type of lever that rotates around a center fulcrum. Ferris wheels, tires, and rolling pins are examples of wheels & axles.

Inclined Plane:

An inclined plane is a plane surface set at an angle to another surface. This results in doing the same amount of work by applying the force over a longer distance. The most basic inclined plane is a ramp; it requires less force to move up a ramp to a higher elevation than to climb to that height vertically. The wedge is often considered a specific type of inclined plane.

Wedge:

A wedge is a double-inclined plane (both sides are inclined) that moves to exert a force along the lengths of the sides. The force is perpendicular to the inclined surfaces, so it pushes two objects (or portions of a single object) apart. Axes, knives, and chisels are all wedges. The common "door wedge" uses the force on the surfaces to provide friction, rather than separate things, but it's still fundamentally a wedge.

Screw:

A screw is a shaft that has a in inclined groove along its surface. By rotating the screw (applying a torque), the force is applied perpendicular to the groove, thus translating a rotational force into a linear one. It is frequently used to fasten objects together (as the hardware screw & bolt does), although Babylonians developed a "screw" that could elevate water from a low-lying body to a higher one (which later came to be known as Archimedes' screw).

Pulley:

A pulley is a wheel with a groove along its edge, where a rope or cable can be placed. It uses the principle of applying force over a longer distance, and also the tension in the rope or cable, to reduce the magnitude of the necessary force. Complex systems of pulleys can be used to greatly reduce the force that must be applied initially to move an object.

The Six Types Of Simple Machines Are Wheel And Axle, The Screw, The Lever, The Wedge, The Pulley, And Inclined Plane.

How did the first pitching machines work?

The first pitching machine was designed in 1897 by Charles Hinton. It was a circular wheel design that was powered by gun powder capable of firing curve balls. It had the ability to throw balls at varying speeds.

How can you make a elf trap with simple machines?

If you mean one of Santa's elves then you cannot trap them by mechanical means as they are magical creatures and can escape any trap you may set. Also Santa's elves are also very good with machines and would not be fooled by any trap you may create.

In order to trap one of Santa's elves you would require a magical containment field or device. You would also need some type of bait which an elf would be interested in. This is incredible hard to find because the elves can make anything they want or have Santa provide for them.

What simple machines are in a calculator?

Ha. That's funny Calculators are electronic. Go ahead, if you don't believe me, open one up. NO STUPId LEVERS THErE, Huh?? What do you think this is, Russia? Idiot.

What are the types of medical scissors?

Basically depends on from which angle you judge it.

Tips: sharp/sharp, blunt/blunt, sharp/blunt

Blades: straight, curved, angled

Cutting Edges: smooth, serrated

Handles: ring, spring, round, flat, bent

Materials: stainless steel, TC, titanium ...

Functions: operating scissors, vascular scissors, iris scissors, corneal scissors, tenotomy scissors ...

Original Designer: Mayo, Metzenbaum ...

What is force distance trade off in a simple machine?

That means that if you use a simple machine to apply less force, you need to compensate by applying the force over a larger distance - for example, to lift up a weight or do some other work.

When trying to move a wheelbarrow across sandy soil would it be easier to push or pull?

Pulling would probably be easier, because the weight is going to try to bury the wheel in the sand. By dragging the wheelbarrow, it may not "nose down" into the sand. But keeping the handles as low as possible might accomplish the same thing.
