Simple Machines (engineering)

An axe is the simplest tool to chop down a tree. Next comes two handle saws. As to a machine - chain saw.

The wedge is one of the six simple machines and may have been the first or second developed (along with the Lever. When early humans made scrapers, axes and knives from stone, they were making a wedge.

1st class lever

Pulley machine type of many! Machine have many pulley, many pulley machine! Type machine, many pulley type. Pulleys, type pulley machine many type. Machine.

it is a wedge because is changes the vertical force into a horizontal force to push the wood apart

Taps and dies are used in threading. To make an internal thread, you drill a hole smaller than the thread width, then slowly screw a 'tap' into it cutting a thread very slowly. -For an external thread, you choose a rod or bolt larger than the final thread, then screw a hard, threaded disc down onto it.

Uh ok ok ok ok

Is it a third class

The most likely cause of a washing machine leak is a small hole in the rubber door seal which can be easily replaced.As a temporary measure the seal can be loosened and twisted 180degrees until the top is at the bottom.

Probably a bad tub bearing. Live with it, or get a new machine.

It won't be the bearing because the shaft is outside of the drum, but it could be a leak on one of the pipe joints, or (as happened on mine) on the pump, which does use a shaft running through a bush and seal from the inside to the outside of the pump body.

Remove the handle, again. Turn the water off at the outside valve and turn another faucet on to relieve the pressure. If you look closely at the stem that the handle screws on to, it has a square area on it that you can put an adjustable wrench on and turn it to the left. The stem will or should come out. There is a seal at the far end that needs to be replaced. Take the stem and all to a local hardware house and they will have a replacement for under two dollars. Now, reinsert the stem and tighen to snug and replace handle. Turn the water back on outside and try it.

A typical brass screw is a threaded rod with a head. It is not a slot at all.

A welding transformer is an electrical transformer used in welding power supply.

It pulls relatively low current drawn from the mains power (typically limited to 15 A to avoid tripping the circuit breaker) and converts it to the typical 50 A to 500 A used in arc welding and higher currents used in spot welding. The main difference between a Normal Step Down Transformer & a Welding transformer , is Not only to Step Down ( lower ) the outlet supply voltage and at the same time increase the Available Output Circuit Current, but to be also able withstand the Short Circuit Conditions on the Welding Output Side and especially for the Magnetic ( Iron Lamination Core ) Part of the Transformer. This Magnetic Path difference prevents the Supply side Electrical Circuit from Oveloading , espcially during the Striking of the Arc, when the Welding Electrode & the Welding Job touch to initiate an Arc, after which the Welding Electrode is lifted slightly by Experience, to maintain the required weld flow. A Normal Transformer of equivalent rating will not be able witstand this operation without burning out.

Class 1.

This is a good one. and it works. fill your empty washer with hot hot hot water, boil some if you have to, put in one gallon of white vinegar, run a wash. When you look in a washer all you see is the outside of the drum what you don't see is all the scum sticking to the inside of the drum, hot water and white vinegar takes care of this

No, they are not.

The edge of a knife separates the material being cut using the principle of a wedge. The edge of the wedge is being forced between the fine structural elements of the material being cut using the action of the simple machine we call a wedge.

First I would like for you to know that I own and operate an Alarm Installation Co., and a 24hr Monitoring Station. As far as building an audible burglar alarm system cheap and simple for a house, the first thing that needs to be done is to determine what it is that you are trying to protect. For instance, putting motion detectors in the living room, and master bedroom is a must. It is these two rooms that most of your valueables are kept. Entertainment equipment is most often found in the living room, and personal valueables are found in the Master bedroom. If you install, or have installed a CPU, master keypad, power supply, backup battery, and a siren, you will have completed the alarm system except for Door, window, motion, glassbreak devices, etc. These will be the devices you will need to protect the residence. How many and which ones will be determined by what you want to protect. For example; A motion detector will provide complete coverage of any room, including the windows, as long as it is armed. However, when you are in the house, such as when you are asleep, the motions are turned off to prevent you from setting off your own alarm if you wake up to go to the bathroom or get a drink of water, so in this circumstance, you lose the protection from the motions. You also need to have an entry/exit door device to allow for the delay time to arm and disarm upon exit or entry of the house. There are many varibles in determining security protection of a home, but the alarm system does not have to bankrupt you to protect the house. I give my customers a free estimate and explain everything that they need to make an educated decision on what type of system they want, and I make it affordable. To many National co.'s advertise low prices and when they finish you get a bill for your first born, an arm, and a leg. I hope this is helpful, contact me if you have any more questions.

Simple machines make work easier by converting one form of energy exertion to another, such as tugging instead a rope with twice as much string but twice the resistance as in a pulley system. Wedges work by pushing down to move objects aside, usually to allow the user to at the same time work with gravity (i.e. not when cutting down a tree with an axe), using more strength but less distance.

Each simple machine uses these conversions/compromises for user convenience, but in reality the total work is nearly constant but risen due to work wasted as friction (heat released to atmosphere).

The very centre of the bulb itself is the Hot contact. The screw in base is the neutral connection.
