annotation

This lesson is held when studying the topic: "Machines and work" with studentsIIIcourse (1 semester) in the specialty110809 "Mechanization Agriculture ". The lesson was developed according to the textbook Bgashev V.N., Dolmatovskaya E.Yu. English for students of engineering specialties.Students have already passed the basic stage of training in the discipline, and already have sufficient knowledge of lexical and grammatical material to study a professional English language program. The lesson is intended for an advanced stage of training in English language and provides a communicative professional orientation of training. On this topic, students have already studied the basic lexical and grammatical material, so the type of lesson issystematization and generalization of knowledge. All stages of the lesson are built on uniform methodological principles, develop the main types of foreign language speech activity, form the intercultural competencies of future specialists. The lesson uses the technology of communicative learning and the technology of learning in cooperation, as well as the technology of critical thinking. To achieve this goal, cognitive methods of motivation, volitional methods (self-assessment and correction, reflection of behavior), as well as the brainstorming method are used. At the stage of building a project, students are encouraged to use, as a technique, mental map(Mind map). Particular attention was paid to the study of the lexical aspect, since the student must be able to translate professional texts, communicate on professional topics; independently improve and replenish vocabulary.

All stages of the lesson contribute to the development of speech, language and professional competence and the achievement of educational and educational goals.The subject of assessment is the skills and knowledge provided for by the GEF in the disciplineEnglish language aimed at the formation of general and professional competencies.

Appendix 5

Of course, depending on the gun. Some are a lot more simple than others. All are “simply” machines, but not all are “Simple” machines.

A matchlock, from the 1600's was simple, very simple, and a modern electric gatling gun, not so simple.

Col. Colt literally went broke because his first revolver, the Paterson Colt was not simple enough.

He built a large supply of revolving guns, on credit, then tried to sell them to the U.S. Army, who rejected the gun as being too fragile and too complex for use in the field.

The existing muzzle-loading pistols only had 3 moving parts, all simple to get to and to repair.

The Paterson had no trigger guard. Rather, the trigger was recessed in the frame, and when the hammer was cocked, the trigger was pushed out where it could be squeezed.

Also you had a revolving cylinder, and linkage with the hammer to move the cylinder and to index the next chamber with the barrel.

And there was added linkage from the hammer, to push the trigger out into firing position and retract it afterwards.

It had well over double the number of moving parts of a single-shot, requiring more parts inventory in the field, and repairs only by a skilled armorer, when something quit working, plus the possibility of powder fouling or mud jamming the cylinder. A very few initial guns were bought as a trial, then the design was rejected completely.

So, he couldn't sell his guns to the U.S. Army, and worse than THAT, they acquired a stink that kept them from selling in the civilian market.

Since they weren't good enough for the Army, why would anyone else want one?

That was until The Republic of Texas came along.

Until that time, Colt Patent Firearms was nearly done for… they were already entering bankruptcy proceedings. `

Texas put in a large order, pretty much emptying that warehouse full of guns that nobody wanted except Sam Colt's creditors.

The first thing was that the immediate money from that order saved Colt from bankruptcy by the skin of his teeth.

The next, more important thing was that The Texas Army, Texas Navy, and (especially) The Texas Rangers used them, which created the civilian market that the U.S. Army had destroyed for him.

In The Battle Of The Bay Of Campeche, the Texas Navy defeated the Mexican Navy, and as a nod to The Republic Of Texas, Colt produced the model 1851 Navy with an engraved cylinder standard, depicting this naval battle.

In addition, to creating a market, the Rangers found a few design flaws, so Captain John Coffee Hays and Capt. Samuel Walker ( The Walker Colt) went to Connecticut with plans for design changes.

The result was The Colt Patterson #5 Holster model, marketed by Colt as “The Texas Paterson”.

The original concept was that the Paterson was an infantry weapon. When you fired your five shots, you could lay flat on the ground, partially disassemble it for reloading, then re-assemble and go on fighting.

The most important use of Colt Revolvers was by The Texas Rangers, who often had to fight Indians on horseback.

To reload the gun, you had to remove the barrel wedge, then remove the barrel, then stuff powder and ball into each chamber with a special supplied tool, then follow those steps in reverse.

If the cylinder, barrel, or barrel wedge fell out of your hands, the gun was useless.

Most Rangers got around that by wearing a sash around their waist and sticking loose parts in there while they just switched in a spare loaded cylinder.

That was in addition to carrying two revolvers, so they had a better chance of getting through an encounter without having to actually stuff powder and balls into the chambers to reload.

So the two most major changes the went to Sam Colt with was to increase caliber from .28 to .36 and produce a different shape on the grip.

Then two years later, Captain Hayes campaigned for the addition of a loading lever, and a capping port in the rear, so no disassembly was required to reload on the back of a galloping horse. Colt made the change to the Texas Paterson.

The Comanche sometimes wore breastplates made of 18-inch lengths of reeds packed in dried mud, and this would often stop a light little .28 caliber ball.

Captain John Coffee Hayes (Called “Devil Jack” by local Indians) first introduced The Comanche to Colt Patent Firearms at The Battle Of Enchanted Rock, in 1841.

He was a surveyor by trade, and climbed to the top of the highest feature in the area, (Enchanted Rock) to have a good look at the lay of the land.

Unfortunately, Enchanted Rock was sacred to both the Comanche and Tonkawa tribes, who believed that evil spirits lived there and are rumored to have made human sacrifices at the base of the rock to keep from getting on the bad side of the spirits. The Comanches caught him alone up there.

In a 3-hour solo battle, he killed them until they took refuge in caves at the base of the rock.

How many of them he killed, before they hid from him, depends on whom you ask, but the lowest count is 15.

Enchanted Rock was already believed by them to be home to evil spirits, and they became convinced that those spirits were on the side of Hays, or that he was actually one OF them.

He had two Texas Patersons, a rifle and a Bowie Knife with him.

Standard Indian tactic was to goad a Ranger into shooting OR shooting AT three of them in quick succession, then charging in for a kill before any reloading of his two pistols and a rifle could happen.

That's how it worked with two single-shot pistols and a single-shot rifle.

Enchanted Rock was their first exposure to someone who could fire 11 shots without reloading.

At one point, he killed a couple of them climbing up after him with his Bowie Knife, another piece of standard equipment for Rangers.

Or. However, some of the most important and useful machines are quite simple. In fact, scientists even call them simple machines!

So what is a simple machine? Is it a machine that does a simple , such as addition or ? Maybe it "s just a machine that"s really easy to operate, like an old television remote control? Or could it be any machine that makes life easier?

While simple machines do make our lives easier, they "re much older than either television remotes or calculators. Simple machines are some of the first machines ever created.

Since the earliest human beings walked on Earth, they looked for ways to make the of everyday life easier to accomplish. Over time, they did this by inventing what has become known as the six simple machines.

Wedges are moving inclined planes used to lift or separate. Wedges are usually used to cut, tear, or break an object into pieces. Common wedges include knives, axes, saws, scissors, and shovels. However, wedges can also be used to hold things in place, such as in the case of staples, nails, shims, or doorstops.

A is a twisted version of an inclined plane. It allows movement to be translated into an up or down motion that takes up less space. Screws can also help hold things together. Common examples of screws include jar lids, drills, light bulbs, and bottle caps.

These six simple machines are all around us. Often more machines, also called machines, consist of one or more of the simple machines put together. Can you imagine how much easier life became after the invention of these simple machines?
